How to wet sand a car - Time Lapse Video


Back in March of this year, (2013), I did a complete wet sand, cut, polish and even machine waxed a 1964 Chevrolet Malibu and while doing this project, Yancy set the GoPro camera up to take a picture every minute.

It's been in queue for editing since then but I'm happy to announce it's now been edited and uploaded to our YouTube Channel.


How to wet sand a car in 8 minutes




Here's the steps I followed...

Covered windshield using the Beach Towel Tip.

Covered interior and convertible top with Eco-friendly drop cloth.

Removed easy to access chrome emblems and script.

Wiped entire car down with Wurth Clean-Solve per what I wrote in post #5 here.

Taped-off all edges and raised body lines using 3M Blue Vinyl Tape. Tape-off video here.


Machine sanded all body panels using a 2-step system

First sanding step: I used 3M Trizact #3000 Grit Discs. I used 3" discs for thin panels and around edges and body lines. Used the 6" discs for the major flat sections of each panel.

Second sanding step: I used 3M Trizact #5000 Grit Discs. I used 3" discs for thin panels and around edges and body lines. Used the 6" discs for the major flat sections of each panel.


Removed all sanding marks.
For this I used the new Meguiar's M100 Pro Speed Compound with a LC Wool Cutting pad on the Flex PE14. At the time I did this project back in March of 2013 this compound had just been introduced to the market, so it was a new compound and I think this is the first car completely sanded and compounded and caught on video using M100 Pro Speed Compound. Speed on the Flex PE14 = 1000 RPM.



Removed any swirls left by the wool pad and the compounding step.
For this I used Meguiar's M205, the follow-up polish for M100 with a 6.5" Lake Country Flat Foam Polishing Pad on the Flex PE14. Speed on the Flex PE14 = 1000 RPM


Finish Polished to maximize gloss and ensure no holograms
After using the rotary buffer with the M205 I re-polished every square inch of paint using Pinnacle Advanced Finishing Polish with a 5.5" Lake Country Foam Flat Finishing Pad on the Porter Cable 7424XP on the 6.0 speed setting.


Machine Waxed
After wiping all the finishing polish off I machine applied Pinnacle Souveran Paste Wax using the Porter Cable 7424XP with a 5.5" Lake Country Foam Waxing Pad on the 4-5 speed setting.

Removed Wax
I removed the wax wearing microfiber gloves and using super soft rolled edge microfiber towels.



Comments....
I wanted to document not only the process but how long it would take me to do this type of project all by myself working non-stop. If you watch the video you'll see around the 4:47 time stamp that the car has now been turned around and is facing forward in the garage.

Here's what was going on...

While I did the actual work non-stop, as in once I started in the morning I did not stop till end of day, I did have to spread the work out over two days as I have too many other job duties to process outside of the garage.

The first day I sanded all the horizontal panels and the driver's side panels. The second day I turned the car around and only had to sand the passenger side.

In a number of places you'll see me standing while I either sand and buff or sitting on the floor while I sand and buff and the reason for this is we don't have a car lift in our garage and proper technique when sanding and buffing is to always be looking across from the paint you're working on. This is especially true when sanding and compounding. I always say,

If you can't bring the car up to you, (with a lift), then you have to lower yourself to the car"


The entire process from start to finish as I listed the steps above except for the initial wiping down of the car with a waterless wash and removing the chrome trim took me approximately,

12 Hours

I hustled the entire time. Only a few times did I stop to either take a water break, switch to different products or pads, or talk to someone that may have entered the garage.


I don't recommend ever trying to do this type of work in a hurry as you'll make mistakes so I didn't hurry but I did hustle. Time is valuable for all of us and I did this during business hours so another reason I had to hustle is because when working in the garage, other job responsibilities are on standby.


Besides this time-lapse video of completely sanding and buffing out an entire car, I think the first time this was ever caught on a GoPro camera using time lapse video was when a team of guys and myself did the full wet sand, cut and buff to a 1969 AMX in November of 2012 as documented in this thread,

Time Lapse Picture Capture of the 1969 AMX Nebraska Project



This was a fun project and I hope you enjoy the video.

It was cloudy the day Mike Gelter brought his 1964 Chevy Chevelle Malibu Convertible to Autogeek but I did take a few before pictures to show the current condition of the paint.

Under the cloudy sky you can see the orange peel, it actually looks worse under fluorescents and if I can find the "before" pictures I took under the florescent lights in the studio I'll add them to this thread...

IF you look closely you can see dieback in the paint, that's where the paint shrinks back into the prep sanding marks in the primer. These all sanded and buffed out.

Beauty Shots
Until then, here's the beauty shots. I machine sanded twice, compound with wool and rotary once, polished with rotary and foam once, polished with a DA polisher once and then machine applied Pinnacle Souveran Paste Wax.

You sanded with 3000 and 5000 to remove the orange peel? It came out really nice. Was it repainted?

I think I counted two water breaks in 12 hours. Sheesh..., thats a few. Well good for you for hustling through.

It was a great video and nice to watch.

Thank you for it,

Art
 
You did all of this in 12 hours? I'd still be taping the car.

Although wet sanding an entire car is probably something I would never attempt, I really enjoy watching someone with your skills do a job like this. I have no doubt that during your short lunch break you also managed to record the entire band track used in the video, and played all of the instruments. Nice work on the drums, by the way. :)

Yes. This was a single stage catalyzed urethane paint job. Same guy that painted this also painted the 1928 Model A Hotrod we're using in the Detailing Boot Camp Class this weekend.

I think I counted two water breaks in 12 hours. Sheesh..., thats a few.

Actually I took a lot more than that, you just don't see them as I didn't hold the glass up to the camera each time. If I remember correctly, the point about holding the water glass close to the camera right before it takes a picture is to remind people to stay hydrated when doing any intense detailing project. You sweat a lot and you need to replenish yourself to maintain your energy and efficiency.

The GoPro flashes a visible light each time it takes a picture, so if I wanted to share something I would just hold it in front of the camera until I saw the flash and after the flash went off go back to work.

It was a great video and nice to watch.

Thank you for it,

Art


Thanks Art.

I personally think it came out really nice. For YEARS I've had people ask for a video on how to wetsand a car but no one is going to watch 12 hours of video.

With this time lapse video you can actually see each of the steps and the order they were done. You can also "stop" the video at any time to get a better look.


It's a LOT of work to sand down an entire car and not make any mistakes. I only know a few other guys that do this type of work.



:)
 
Wow, you were hustling! A car that size would probably take me 20+ hours to cut and buff. Great job!

Were there any runs or other bad spots that required more sanding? Or just 3000 then 5000 to knock down the texture?

My first brand new car, a red 1964 Chevy Chevelle Malibu SS, 4 on the floor with a high revving 283 ci V8.

I think the sticker was around $3,200. Sure brings back some memories,

Thanks Mike, great job.


:dblthumb2:
 
You did all of this in 12 hours? I'd still be taping the car.

Yes, at least approximately. I had to take a few breaks and for these I would turn the camera off. I did keep a clock on the car throughout the entire process and kept track of the hours I worked.

I wouldn't recommend anyone try this at home but this was really the only way I could do it and justify the time away from other responsibilities.

Although wet sanding an entire car is probably something I would never attempt, I really enjoy watching someone with your skills do a job like this. I have no doubt that during your short lunch break you also managed to record the entire band track used in the video, and played all of the instruments. Nice work on the drums, by the way.

I think the music soundtrack was performed by our very own in-house genius and that would be Yancy. I think he plays every type of musical instrument as he's very talented.

All my life when I've detailed cars I pretty much start early and don't stop till the final wipe... It's not a great "style" but doing projects like this one takes both a lot of time and concentration and every minute you're goofing off, or getting a glass of water, there's work not being done.



Were there any runs or other bad spots that required more sanding? Or just 3000 then 5000 to knock down the texture?

There were two runs, one on the driver's side lower body panel and one on the passenger side lower door and I knocked these out after the fact using a Unigrit Block. Didn't what the "time" it took to interfere with the "big picture" of capturing the entire process from start to finish on video.

Mike,

I recently purchased the Flex PE14 rotary buffer and it came with the 6" flexible yellow backing plate. I noticed that you were using an extension on your Flex and what seemed to be a different type of backing plate. What exactly did you use and any particular reason?
 
I'm just a novice at detailing but I assume that wet sanding removes the clear coat and only the base coat remains. It must be more important that a good coat of wax/sealant be maintained on the base coat after wet sanding.

The extension you saw started out in the detailing world as an

Adapter

See this thread...


I use it as an extension to get get the body of the buffer away from the buffing pad so I can,

A: More easily see what I'm buffing.
B: Get into tight, intricate areas.
C: Clean pads easier when using a pad washer.


See these articles for very thorough and in-depth information on the above...

Video: Tip for cleaning pads in a pad washer

I took this picture some time ago to show how you can use an adapter or extension on a rotary buffer to make cleaning a pad easier when cleaning pads in a pad washer.

As for the white backing plate it offers a lot of flex or cushion so I prefer it for this reason. The yellow one you recieved is also a flexible backing plate just not as much cushion as the white one.

Good questions and we'll be using a lot of these tools tonight when we sand and buff the 1928 Model A here at Autogeek.

All of the clear coat is not removed. It is just the "peaks" of the orange peal that is removed to level down to the "valley's". At that point the clear coat is polished back to a brilliant shine. This all must be done delicately as the clear coat is SUPER thin.

Pefect answer Kevin...


By the way, Frank lives in South Florida and he joined us last Thursday night and has his first chance to see what wetsanding is all about...

Pictures: 1928 Model A - Wetsand, Cut and Buff at Autogeek



Frank's First Time
Here's Frank learning all about how to wetsand, cut and buff fresh paint here at Autogeek's Show Car Garage!

This was Frank's first visit to our Thursday night gigs and he picked an great night to join us as not only did he get to see the entire process from sanding, cutting, polishing and machine waxing a very cool traditional hot rod but he also was able to helps us restore the original paint on a 1956 Chevy Bel Air.

Wow!! That no doubt is the Pinnacle of all time lapse sand, cut, polish, wax & detail videos.

As usual, you're setting and raising the bar.

Awesome video Mike!!
