This was my first time trying to do my own detailing. I decided to do it myself because I am very particular and the reviews I saw from the detailers were terrifying. So I thought I would take better care of my own.

I have a 2011 E350 - I read the article about Cerimaclear paint as it was recommended reading from some of the board members. I watched most of the videos here and felt comfortable enough to try it until I did it today.

I purchased all of the equipment as recommended from different topics.

A Porter Cable 7424XP
Chemical Guys Orange, White and Black Foam Pads

I read the advice about getting the least aggressive so I purchased
Meguires Mirror Glaze M2 Fine Cut Cleaner
Meguires M2 Glaze Swirl Remover
Mothers Reflection Car Wax

The washing and the claying went just fine BUT when I did the polishing things must have gone wrong. My car now has more swirls and scratches then it had before after. So I am not sure what I did wrong and how I should fix it.

I watch all of the videos and read tons of articles to where I felt comfortable enough to go ahead and work on my car as I felt that it would be pretty safe.

Did I maybe polish to long or use too much polish? I used 3 dime size drops as it was on the videos (at the very first it splattered everywhere even though I didn't turn the Polisher on until the polisher was on the car.)

Needless to say I feel horrible right now. I could use any advice how to maybe fix this or what products to use so I can fix it.
 
Dang im sorry that happened. Dont worry though you got the tools to fix it your self. The color of the car would be useful as well as a picture. First thing first though this is why its crucial to do a test spot. What pad and products did you use and in what order?
 
I think you possibly meant Meguiar's Mirror Glaze #9 Swirl Remover

Neither of these products (#2 or #9) has much cut at all.

Did you "prime " the pad or did you just put three dime sized drops and start polishing.


If you were using the Orange pad and did not prime properly, it is possible that you were dry buffing, which can indeed damage paint.


I suspect that the defects in the paint may have always been there and were exposed by a good washing, claying and the chemical cleaners in the Meguiar's products.

I doubt the paint has more "scratches" of significant size even after dry buffing with #9 and an orange pad with a PC.


Post some pictures and you will get more specific advice.

Also a thorough description of the scratches would be helpful.

I use 6 pea size of product when I am using a polisher and a cutting compound. I use speed setting 1 to spread the product on a 2'x2' area at a time. Once I have spread it evenly I bump up the speed to 5 making three to four passes overlapping each pass 50/50. I make my passes horizontal from top to bottom and then vertical passes overlapping from where I left off. At least you did not burn some area of the paint like my brother did when he tried it for his first time.

It was actually washed when he did the work....from what he told me. I did this job while I was out on a flight, I almost cried when I saw it since I felt sorry for the car not for him.
 
Those do not look like defects that were inflicted by a machine. They are too long, too straight and not uniform enough.

I suspect it is from someone doing a Dukes of Hazzard slide across the hood or some other asinine move.

I have also seen a pattern like this where someone put a large, heavy cardboard box with a dirty bottom on their trunk lid and then slid it off.

There are also swirl marks clearly visible in the lower right of the photo and a large RIDS in the middle of the photo that lead me to believe the area has not been compounded at all.

You Brother may have "Tom Sawyered" you into polishing his car.

To be honest I have some of my friends that are studying to be Forensic Scientist helping come up with a possible explanation and yours seem to fit. I he has some of these around his car.
 
It is black. I will have to take pictures tomorrow. I spent all day on this car by the time I got done it was dark. I didn't wax it since I was frightened I wasn't doing something right.

I did prime the orange chemical guys hexlogic pad using Mike Phillips technique by spreading polisher like butter on the pad. I used the fine cut first.

I did clay the car first since the first car detailer pointed out to me that I had "over spray" but I honestly felt as he probably caused some of it. I washed the car really good and couldn't feel the grit as I felt it when the first detailer "pointed" it out to me.

One thing I did is whenever i finished a section I added the 3 dime size drops on to the pad. Am I using too much product? Also is the polish suppose become some what clear?

I tried to be as careful as possible but now I have to really get my stuff together because I need to fix my car. It just looks like it has a bunch of swirls and scratches that become real apparent in the light, I didn't notice it at first with the little day light that was left (it actually looked shiny).

I just want to be sure that I follow on the right steps. It's a lot to read and watch. The videos seem so much easier, it wasn't like this for me LOL.

The first pass, I had splatter everywhere and probably spent an hour getting it off my windshield and the car next to me.

Should I have gotten the Wolfgang or Merzana type polishes instead of the Meguire?

Thanks for on the responses

Sorry, yes that is the one. I have just been doing so much research and there are so many different numbers for each product I am still learning.

I did prime it. I put a circle of polish around the pad then used my finger to spread it over the pad even the edges (Saw it in Mike's video here)

My car looks similar to this one with the swirls and scratches and has some smudges.

You probably just need to do a polish even better would be to do a ultra fine polish since the car is black. The porter cable is really user friendly.

I am not to familiar with the products you listed above, but just a polish and an ultra fine polish with a polishing pad followed by a waxing pad should do the trick.

For the splatter there shouldn't be any. If there was splatter you are either using WAY too much product or you didn't smear it. Here's what I do. Once product is on the pad I place it on the car and smear it around then I turn the buffer on using speed 1 then I go to speed 2 until the product covers the working area then I jump up to 4-6.

The products you are using are pretty mild. To be honest megs #9 did nothing when I used it but all cars are different.

In my opinion a good combo when you're starting out is Wolfgang total swirl remover 3.0 and then their glaze since their glaze apparently has a very fine cut to it.

Don't get overwhelmed though. We are all here to help and we will make sure you get it done. Everyone of us started out not knowing a thing about how to detail a car. But by trial and error we got where we are today.

Report back with some pics tomorrow and we will get to the bottom of this :)

This was my first time trying to do my own detailing. I decided to do it myself because I am very particular and the reviews I saw from the detailers were terrifying. So I thought I would take better care of my own.

I have a 2011 E350 - I read the article about Ceramiclear paint as it was recommended reading from some of the board members.

That would be my article warning people not to get very aggressive with Ceramiclear paints and to be on the look out when buffing out cars already detailed by someone that WAS NOT careful with the Ceramiclear paint.

For those reading this into the future, here's the link to this article.

Ceramiclear Paints - Be Careful




I watched most of the videos here and felt comfortable enough to try it until I did it today.

I purchased all of the equipment as recommended from different topics.

A Porter Cable 7424XP

What is the diameter and thickness of the CG pads? Here's the deal,

Thin is in...

Anytime you're using a Porter Cable or a tool that is a copy of the Porter Cable you really want to be using thin pads and small diameter pads. I cover this in my how-to book and multiple articles on this forum.

Thick, large pads rob the power coming out of these types of tools to the point where the tools cannot effectively maintain pad rotation especially as you work around the car and the pads become wet with products.

Wet pads rotate worse than dry pads. This is why you need more than ONE pad to buff out a car. In fact, more pads are better.

This is also why you need to mark the back of your backing plate somehow so your eyes can see if the pad is rotating or not.

From reading through your post, the problems could all be technique related....

The #2 Fine Cut Cleaner is a medium cut polish that can remove substantial swirls and scratches with a foam cutting pad and good technique.

The #9 Hi Tech Swirl Remover is a fine cut polish and can refine the finish left by the #2 to look look better before sealing with a wax.

That said, there are much better polishes for this type of work at least newer technology. If you're a Meguiar's guy the get the Ultimate Compound and Ultimate Polish.

Another product recommendation that works very well with the Ceramiclear paints would be the Wolfgang Uber Compound and Wolfgang Finishing Glaze. See this article,

The Wolfgang Four


Here are four products that will take care of about 99.9% of any exterior paint correction product you'll ever have in your garage.


The Wolfgang Four
The_Wolfgang_Four.jpg



Forum member RFulmer coined this term, (due credit where credit is due), and since there's been a lot of questions about what each product is, what they do, the order of aggressiveness and when you use one over the other, here's some info...



Uber Compound
  • Aggressive Compound - More aggressive than Wolfgang Total Swirl Remover and Wolfgang Finishing Glaze.
  • For use with any type of polisher/buffer and can be used by hand.
  • Body Shop Safe = Can be used in a fresh paint. environment (body shop) and can be used on fresh paint, (paint just sprayed and less than 30 days old).
  • Safe for Ceramiclear paints.
  • Cafe for all clear coat paints.
  • Safe for all single stage paints.
  • For some people on some cars it can be used as a compound/polish after which the paint can be sealed with a wax or synthetic paint sealant.


Total Swirl Remover
  • Medium Cut Polish - Less aggressive than Uber Compound and more aggressive than Wolfgang Finishing Glaze.
  • For use with any type of polisher/buffer and can be used by hand.
  • Body Shop Safe = Can be used in a fresh paint. environment (body shop) and can be used on fresh paint, (paint just sprayed and less than 30 days old).
  • Safe for Ceramiclear paints.
  • Cafe for all clear coat paints.
  • Safe for all single stage paints.
  • Should be tested before using Uber Compound to see if it will remove defects to our satisfaction in keeping with the practice of using the least aggressive product to get the job done.


Finishing Glaze
  • Fine Cut Polish - Much less aggressive than Wolfgang Total Swirl Remover and of course dramatically less aggressive than Wolfgang Uber Compound.
  • For use with any type of polisher/buffer and can be used by hand.
  • Body Shop Safe = Can be used in a fresh paint. environment (body shop) and can be used on fresh paint, (paint just sprayed and less than 30 days old).
  • Safe for Ceramiclear paints.
  • Cafe for all clear coat paints.
  • Safe for all single stage paints.
  • Should be tested before using Wolfgang Total Swirl Remover to see if it will remove defects to our satisfaction in keeping with the practice of using the least aggressive product to get the job done.
  • Great "Maintenance Polish" for use removing shallow swirls that show up over time from normal wear-n-tear on daily drivers and after a person has already performed a multi-step procedure to remove serious paint defects.


Deep Gloss Paint Sealant 3.0
  • German engineered synthetic paint sealant.
  • Non-cleaning, pure synthetic - Paint must be in excellent condition as in brand new or previously polished to like new condition before use.
  • Can be applied by hand or any type of dual action polisher wit foam pads.
  • This product "seals" the paint in the say way a car wax or paint coating will seal the paint. It is water insoluble and as such like all synthetic paint sealants, car waxes and paint coatings is not body shop safe.
  • Requires 30 to 45 minutes of drying time before removal.
  • Oxygen activated. After buffing off the excess sealant the remaining protection ingredients should be allowed to cure and fully set-up for an approximate 12 hour window of time before the vehicle is put back into service where it will be exposed to water.


Synergistic Chemical Compatibility
Each product is chemically compatible and chemically beneficial when used as a system approach to take a diamond in the rough and turn it into a glistening gemstone. Using the entire line in the correct order or just a few of the product in the correct order is an example of working forward in the paint polishing process.


All Inclusive System-Approach
This group of four products with just about any tool, any pad and even by hand will produce not only show car results but do it consistently across a VERY wide spectrum of paint systems including,
  • Hard paints, soft paints and everything in-between.
  • Factory OEM paints and aftermarket repaints at your local body shop or custom paint shop.
  • Single stage and basecoat clearcoat.
Which products do you need?
Which product you'll need depend upon the condition of the paint on the car. Click to my list of paint condition categories and read through the descriptions for the different categories. Then after washing and drying your car, inspect the paint both with your sense of touch, (The Baggie Test), and visually with your eyes in bright light for swirls and scratches.

Then determine which category your car's paint fall into. Here are some general guidelines but the best way to determine which exact product you'll need to remove the defects and restore the finish on your car to your expectations can only be determined by doing a Test Spot

I use 6 pea size of product when I am using a polisher and a cutting compound.

I always laugh when I see someone say they are using Pea Sized Drops.

I've been buffing out cars all my life and I never used peas sized drops. In most cases it's not enough product especially when buffing out 2' by 2' sections.

But that's also a mistake with the Porter Cable type tools. a 2' x 2' section is TOO LARGE.


I use speed setting 1 to spread the product on a 2'x2' area at a time.

Once I have spread it evenly I bump up the speed to 5 making three to four passes overlapping each pass 50/50.

2' x 2' area is too large.

Speed setting 5 on the PC is too slow ESPECIALLY if you're using thick, large pads. My guess is the pad was barely rotating and thus not doing anything to correct the paint.

3-4 passes for the damage you show in the picture is not enough. You need to do more like 6-8 with FIRM downward pressure like discussed in this recent thread.

Downward Pressure....What is "Moderate"?



I did prime the orange chemical guys hexlogic pad using Mike Phillips technique by spreading polisher like butter on the pad. I used the fine cut first.

That's actually the Kevin Brown Method of priming a pad. I like it and think it makes good sense and so I share it with everyone but I always give due credit where credit is due. I never steel or borrow other guys information or techniques and present them as my own as a part of being honest. I don't see this all the time on the part of other guys but I can't control what they do.



I just want to be sure that I follow on the right steps.


Read this carefully and look for mistakes you might be making. I always suggest to people to read this article FIRST and then you can avoid making the mistakes in the first place.

A few years ago after I wrote this someone suggested this be printed out and included with every dual action polisher sold. I agree. It would help to insure success by people new to machine polishing. That is if they read it.


DA Polisher Trouble Shooting Guide



Tyler, age 15 removing swirls using a Porter Cable 7424XP Dual Action Polisher
1965Plymouth035.jpg



When you're first starting out machine polishing and learning to use a DA Polisher it's common to have questions about your results and your results are directly tied to your technique.

Here's a list of the most common problems,

1. Trying to work too large of an area at one time.

2. Moving the polisher too fast over the surface.

3. Using too low of speed setting for removing swirls.

4. Using too little downward pressure on the head of the polisher.

5. Using too much downward pressure on the head of the polisher so the pad quits rotating.

6. Not holding the polisher in a way to keep the pad flat while working your compound or polish.

7. Using too much product or using too little product.

8. Not cleaning the pad often enough.
Here's a list of the solutions in matching order,

1. Trying to work too large of an area at one time.
Shrink the size of your work area down. You can't tackle to large of an area at one time. The average size work area should be around 20" by 20". Most generic recommendations say to work an area 2' by 2' but for the correction step, that's too large. You have to do some experimenting, (called a Test Spot), to find out how easy or how hard the defects are coming out of your car's paint system and then adjust your work area to the results of your Test Spot. The harder the paint the smaller the area you want to work.


2. Moving the polisher too fast over the surface.
For removing defects out of the paint you want to use what we call a Slow Arm Speed. It's easy and actually natural for most people new to machine polishing to move the polisher quickly over the paint but that's the wrong technique. One reason I think people move the polisher too quickly over the paint is because they hear the sound of the motor spinning fast and this has psychological effect which causes them to match their arm movement to the perceived fast speed of the polisher's motor.

Another reason people move the polisher too quickly over the paint is because they think like this,

"If I move the polisher quickly, I'll get done faster"

But it doesn't work that way. Anytime you're trying to remove swirls, scratches, water spots or oxidation using a DA Polisher you need to move the polisher s-l-o-w-l-y over the paint.



3. Using too low of speed setting for removing swirls.
When first starting out many people are scared of burning or swirling their paint, so they take the safe route of running the polisher at too low of a speed setting but this won't work. The action of the polisher is already g-e-n-t-l-e, you need the speed and specifically the pad oscillating and rotating over the paint as well as the combination of time, (slow arm speed), together with the abrasives, the pad aggressiveness, and the downward pressure to remove small particles of paint which is how your remove below surface defects like swirls or scratches.

Removing below surface defects is a leveling process where you need the abrasives to take little bites out of the paint and to get the abrasives to take these little bites with a tool that uses a Free Floating Spindle Bearing Assembly you need all of the above factors working for you including a high speed setting.



4. Using too little downward pressure on the head of the polisher.
For the same reason as stated in #3, people are scared, or perhaps a better word is apprehensive, to apply too much downward pressure to the polisher and the result of too little pressure is no paint is removed thus no swirls are removed.



5. Using too much downward pressure on the head of the polisher so the pad quits rotating.
If you push too hard you will slow down the rotating movement of the pad and the abrasives won't be effectively worked against the paint. You need to apply firm pressure to engage the abrasives against the paint but no so much that the pad is barely rotating. This is where it's a good idea to use a permanent black marker to make a mark on the back of your backing plate so your eyes can easily see if the pad is rotating or not and this will help you to adjust your downward pressure accordingly.

Correct technique means finding a balance of applying enough downward pressure to remove defects but not too much downward pressure as to stop the rotating movement of the pad.

This balance is affected by a lot of factors like the lubricity of the product you're using, some compounds and polishes provide more lubrication than others and this makes it easier to maintain pad rotation under pressure.

Another factor that can affect pad rotation are raised body lines, edges and curved surfaces as anytime you have uneven pressure on just a portion of the face of the pad it can slow or stop pad rotation. This is where experience comes into play and experience comes from time spent behind the polisher.



6. Not holding the polisher in a way to keep the pad flat while working your compound or polish.
Applying pressure in such a way as to put too much pressure to one edge of the pad will cause it to stop rotating and thus decrease abrading ability.



7. Using too much product or using too little product.
Too much product hyper-lubricates the surface and the result is that abrasives won't effectively bite into the paint but instead will tend to skim over the surface. Overusing product will also accelerate pad saturation as well increase the potential for slinging splatter onto adjacent panels.

Too little product will means too little lubrication and this can interfere with pad rotation.

Again there needs to be a balance between too much product and too little product and finding this balance comes from reading articles like this one, watching videos an most important, going out into the garage and putting in time behind the polisher and as you're buffing with specific product and pad combinations, pay attention to pad rotation.



8. Not cleaning the pad often enough.
Most people simply don't clean their pad often enough to maximize the effectiveness of their DA Polisher. Anytime you're abrading the paint you have two things building up on the face of your buffing pad,
  • Removed paint
  • Spent product
As these to things build up on the face of the pad they become gummy and this has a negative affect on pad rotating plus makes wiping the leftover residue on the paint more difficult. To maintain good pad rotation you want to clean your pad often and always wipe-off any leftover product residue off the paint after working a section. Never add fresh product to your pad and work a section that still has leftover product residue on it.

Show Car Garage Video: How-To do a "Section Pass" when Machine Polishing with a DA Polisher

Here's how to do a "Section Pass" when trying to remove swirls, scratches and other below surface paint defects.


How to do a Section Pass
[video=youtube_share;Q70g83mnTn4"]YouTube- How to do a "Section Pass"...[/video]​






When talking about machine polishing on discussion forums or even in detailing classes, the below questions always comes up,
  • What's a pass?
  • How many passes do I make?
  • What's a section pass?

The definition of a pass
There are two definitions of the word pass as it relates to machine polishing with any type of machine.


Single Pass
A single pass is just that. It's when you move the polisher from one side of the section you're buffing to the other side of the section you're buffing. That's a single pass.


Section Pass
A section pass is when you move the polisher back and forth, or front to back with enough single overlapping passes to cover the entire section one time. That's a section pass.

In most cases if you're removing any substantial below surface defects you're going to make 6-8 section passes to the section you’re working before you either feel comfortable you've removed the defects or you're at the end of the buffing cycle for the product you're using.


Buffing Cycle
The buffing cycle is the amount of time you are able to work the product before the abrasives have broken down, (if you’re using a product that uses diminishing abrasives), and/or the product begins to dry and you lose the lubricating features of the product. Different products have different buffing cycles depending upon the type of abrasives used in the formula and the different ingredients used to suspend the abrasives and provide lubrication.


Factors that affect the buffing cycle include,
  • Ambient temperature
  • Surface temperature
  • Size of work area
  • Type of machine
  • Type of pad material
  • Humidity
  • Wind or air flow surrounding the car
  • Amount of product used
  • Technique

Wet buffing technique
Most compounds and polishes should be used so that there is enough product on the surface to maintain a wet film while the product is being worked. The wetness of the product is lubricating the paint as the abrasives abrade the paint and cushion or buffer the abrading action so the abrasives don’t simply scour the finish leaving behind swirls and scratches.


Dry Buffing Technique - Buffing to a dry buff
There are some products on the market where the manufacture recommends buffing the product until it dries. As the product dries you’ll tend to see some dusting as the product residue becomes a powder and the paint will have a hard, dry shine to it.

Although some manufactures recommend this, it’s important to understand what’s taking place at the surface level as you buff to a dry buff. As the product dries, in essence you are losing the lubricating features of the product and as this happens friction and heat will increase. As friction and heat increases, so does the risk of micro-marring the paint or instilling swirls either by the product residue or the pad material and/or a combination of both.

While we trust that the manufacture knows their products best, when we take a close look at what it means to buff on a delicate surface like an automotive clear coat, it doesn’t make sense to run a buffing pad on top of the paint without some kind of wet film to lubricate the paint at the same time. We always recommend that you follow the manufacturer's recommendations and use your own judgment.

Everyone new to buffing wants to be told some easily identifiable sign that they can use to tell when it's time to stop buffing and it's not that simple, so here's an indicator I've always used and taught to others,

Wet film behind your path-of-travel
As you're making a single pass with the polisher, the paint behind the path of travel of the buffer should have a visible wet film on it. If the paint behind the pad is dry and shiny, you've run out of lubrication and you're dry buffing. Turn the polisher off. Wipe the residue off and inspect using a Swirl Finder Light to make sure you didn't dull or mar the paint, you usually won't cause any harm, but pay attention when your running the polisher and don't buff to a dry buff. If you do, you can quickly re-polish that section by cleaning your pad and adding a little fresh product and making a few new section passes.


UMR
Remember, in most cases the goal is UMR or Uniform Material Removal. The reason for this is so that you remove an equal amount of paint over each section and in turn over the entire car. In order to do this you need a method that you can control and duplicate and for most people following a back and forth, side-to-side pattern works because it’s easy to remember, easy to do and easy to duplicate.

Aside from the great advice you received from everyone else, look at it this way. You can't go back and change what you already did so no reason to be hard on yourself. Take it as an opportunity to learn.
 
If you post a general location to your profile, you may have the privilege of getting a "geeker" to throw out an invite to assist. I know I would (if you were in Louisiana).

I've done a few black Benz (from minor swirls to major neglect) and I find that I've always had great results with Menzerna products in combination with LC flat pads (on my GG6 and Rupes 21). Here is a quick 50/50 on a neglected Benz

Follow the advice of Mike Phillips to the letter and you will get excellent results.

He has covered every detail in his recent posts.
 
This great! I download Mike's iBook last night and will give it another go after studying all of the helpful advice.

I added the pics of what my epic fail looks like. Please not the clouds are just a reflection of the sky and not my work.

Also question for Mike, I saw the post where you showcased a black 2014 black MZB and it is very similar to mine but you used a bunch of different products, I think the Black Label. Should I just stick with the products you recommend the Wolfgang 4?

Also my foam pads are those ideal for my car? I bought Chemical Guys hexlogic orange, white and black? Or should I get different pads?

Thanks again for all your help guys! Will try again this weekend if it doesn't rain in Atlanta.
