I think I have caused extreme marring in my paint. How would I go about fixing this with a 7424xp? (First time DA polishing)

[imbored408]

It wasnt there before and I guess I screwed up somehow using the 7424XP.

I used M105 with an orange LC pad at speed 5
-Prepped pad with 4 spots then pressed on work area
-3 more spots on pad then started working the paint
-slow movement up-down and then left-right

I also noticed M105 would dry up very quick and would and start giving off polish dust before I could even go through my left-right passes after the up-down passes.

Even after using M205 with a white LC pad at speed 5, I was not able to rid of the marring.


What do?



The car was washed and then clayed before I began polishing. I am surprised the marring occurred since I practiced on a spare bumper and had no problems at all.
I guess the only good news is that the car is old and not worth a lot to begin with..

 

[Eric@CherryOnTop]

Yeah that looks pretty nasty. What kind of car is that? Do you have experience polishing paint? Reason I ask is because M105 is not known as the most user friendly compound on the market. It has a pretty steep learning curve and people reach for it often thinking that their paint is in worse shape than it really is. You can end up doing more damage than you fix. If the product is dusting like you say that means it is drying up and the lubricants in the compound are no longer present. My personal experience with Meguiars SMAT products is that they have a very short, but very fast buffing cycle. You might want to look up the Kevin Brown Method of using M205 on finicky paint systems. Otherwise, perhaps consider switching to a product that is more user friendly, like HD Adapt or Menzerna 2500.

Nissan 1995 240sx. This is my first time ever attempting polishing and first time using a 7424xp. Also I think the defects are actually holograms rather than marring.

The good news is that it seems it can be easily fixed. I don't know how hard the paint is, but M105 is not very good for soft paints, Meg's cutting compounds work better on medium to hard paints, imho.
I would change the cutting compound, what else do you have?

The only other thing I have on hand is M205, and Black,White,Orange LC pads.

I can go to a autoparts store and buy something else if needed, though.

M205 and a white LC Pad should get things in order very nicely.

My obvious first question is...are you sure you caused that marring or was it there from possibly a rotary user before. If you know it is the result of you trying M105 I would want to exhaust an attempt at M205, maybe a black pad and slow arm movements. Start with about 10-15 pounds of exerted pressure for 2 section passes then lighten it up to machine weight only for another 2-3 passes. I like the Kevin Brown method and research that if you're not familiar. Basically you cover the entire pad surface with product and then add about 2-3 pea sized dots and work the section. I also like to have a spray bottle of distilled water handy and spritz the panel at about the mid work point to keep it lubricated if its dusting too much. If the black pad didn't improve things then switch to a white pad.

My guess is you are dealing with softer paint however i would also be cautious of the paint film thickness on a '95!

 

[Eric@CherryOnTop]

You won't get holograms from a DA machine, and if holograms were there before you started, you would have removed them. The defects you are seeing are from what you used on the paint. I would imagine that paint is on the softer side.

Try a white pad, cover the ENTIRE face of the pad with M205, then lightly wipe a clean microfiber towel over the face of the pad. Then use 4 lead sized drops of M205 and polish a 16"x16" section of paint (I would try speed 5 to start). On your last 2 passes don't put any extra downforce on the machine, let the pad "burnish" the paint. Make sure you are using a clean plush microfiber to wipe the polish away, you may very well be susceptible to towel marks too on that paint.

I think I have caused extreme marring in my paint. How would I go about fixi...

How big of an area were you working on? How much pressure were you putting on the pad when buffing? Did you try using m205 first before trying m105? Maybe try prepping the pad better like Kevin Brown does. The paint maybe very soft, so you might have to try a less aggressive approach.

I have never seen those defects before and I had the car for years. Never taken it to an auto car wash or detailer either. I will try the KBM way.

Will try with black pad first.

I did around 2x2 squares throughout the hood. Used about 10lbs of pressure. Started with m105 on an orange pad since there were many scratches but now realize that may not have been necessary...

I am now pretty sure those marks are caused from wiping the polish off. I did a 2x2 square and wiped the polish off with quick detailer and a MF towel moving left to right and saw that those hologram marks were now left to right.
I did the same section except wiped off the polish going up and down, and those hologram marks were now up and down.

Could those marks just be oils and not scratches?

The MF towels are soft and clean so what am I supposed to do now?

 

[emmjay]

I had similar issues on my new Honda.

I hope the picture shows up below.

Either way. All I used was M205 and Black Finishing pad from the Hybrid line and my flex. That knocked it out real good.

And now 3 months after the detail, these types of scratches are back, even though I am extremely careful. However, they are a lot lot lighter and one would have look at it at a weird angle to spot them compared to before where it was in your face. I too feel its the towels and not technique.

I used the same techniques on my previous car, VW gti, and I never suffered towel marring.

What towels are you using?

don't forget not all car paint is the same, some is soft, hard, finicky, so just because it was awesome on your previous ride, it may not be on your current one. Plus Honda paint is pretty soft from what I remember(had an old Honda).

Oh I completely agree. That's why I said on the soft Honda paint, a black finishing with m205 was more than enough to fully detail the car....That combo would not do anything on my previous VW.

I was merely going by the last statement where OP stated that just wiping of polish is causing marring - subaru like - so maybe the towels have previous residue, or are cheap etc.

Ah I see! hard keeping up on the app! m205 and a black pad pretty much is what my Toyota needs as well, soft paint is crappy to have so I feel your pain.

Grab some Megs Ultimate Compound, its sooo easy to use. You can get it practically anywhere too.

 

[Eric@CherryOnTop]

If the marks are showing up concurrent with the way you are wiping off the polish then you probably have some super soft paint and if you sneeze you will scratch it.

My way of dealing with this is to soak a super soft microfiber towel (like a blue wobbie) in rinse less wash solution and use that to wipe off the polish. The rinse less solution will lubricate the towel.

I'm with this guy that is not marring from a polish or pad.

They would be in a more uniform motion consistent with the move of the da polisher.

Those are oils from the polish and you are probably using the same towel spreading the oils around.

Use a water alcohol ratio 80% water 20% ipa use a new towel and it should be gone.

 

[WRAPT C5Z06]

Could be residual oils left over from the polish, but I doubt it.

My guess would be super soft paint, and that's marring from either the pad/polish, MF towels, or both.
