Fixing a bodyshop nightmare

Originally posted on Corvetteforum- The owner of this gorgeous Corvette asked me to document all the damage on the car and do a write up. Since I haven't been doing a lot of click and brags lately, I figured I woudl share it here.

I was contacted by Corvette forum member 14vision who was disappointed with the quality of the work performed on his Corvette and was hoping to have the car look as good as it should.

A quick background on the Corvette. It is a 2007 roadster that was brought to Orlando to have a Caravaggio body kit installed and painted. The car was "detailed" and returned to South Florida. To say the work performed was bad could be an understatment. The car had numerous sanding marks that where incorrectly polished or not polished at all. There was also numerous dust particles or "nibs" in the paint that they had failed to sand.

Also, not only where the sanding marks incorrectly buffed out, but the car had severe, moderate, and mild hologramming across the entire surface of the paint. Also above the tail lights, on the edge of the bumper, was some light burning from the polishing done at the dealership.

Also, we noticed that the sides did not have any sanding marks but they did have holograms. They also had huge amounts of orange peel, and a lot of "nibs" or dirt in the paint and a couple runs. This leads me to believe that no sanding was done on the vertical panels, and no correction of the defects was done from the painting. Even though there is more orange peel because of the lack of sanding on the sides, at least they didn't screw up anything on the sides to bad.

Stories are always better with pictures...

Initial Inspection showed buffer trails (to be expected from any body shop)



However in numerous area's, the paint showed deeper (thicker) defects that turned out to be sanding marks in the paint that where incorrectly sanded and further more incorrectly removed with a polisher.



The arrows are pointing at the deeper, thicker defects...



This picture is out of focus because I was trying to pull the focus on the actual surface of the paint instead of the deeper (and further away) reflections. If you look closely, you can "see" the texture of the paint because of the terrible sanding techniques.





Another picture of the "texture" or sanding scratches on the paint.



Same picture with light blue "highlights" to help show the sanding marks.



We started to mark all area's with the sanding marks with blue tape.



In this picture, which is the same as the above, I highlighted the visible defects.



And in this picture, I highlighted what the surface truely resembled in person.



I adjusted the shutter speed on the camera and was able to better capture some of the defects.





As you can see, even the areas that did not recieve blue tape (to denote sanding marks) had signifcant marring.





The edge of the hood was particularly bad (you can see the severe hologramming to right)



Hurry, we need more blue tape!



And more...



Here is a reflection picture of the hood. Notice the lack of orange peel.



Here is the reflection of the side of the car (notice the heavy orange peel)

Re: Fixing a bodyshop nightmare

More defects...



We started to mark off severe holograms with green tape to get a better image of the defects on the car.



As you can see, there is still hologramming in the sun between the green tape, as the entire car was covered with holograms. We only marked the severe ones.













Again you can see the lighter hologramming that exsisted over the car. If we where to tape every hologram, we would have had to tape the whole car.





The final pictures after taping and paint inspection.







Here is one of numerous "nibs" that where all over the side of the car. Because the orange peel was so bad, if they sanded these out, they would have flattened some of the orange peel, which would the area stand out more.

They should have sanded the entire sides, but given the quality of the their sanding work, it is probably better they did not.



Some pictures of the Corvette recieving surgery.

Re: Fixing a bodyshop nightmare

The process consisted of the following...

-Re sand all sanding mark areas with 2500 grit Meguiars Uni-Grit.

-Sand out numerous "nibs" with 2000 grit Meguiars Uni-Grit followed by
2500 grit.

-Polish with Meguiars M95 using a Meguiars So1o Aggressive wool x2-4
-Polish with Menzerna SIP using a Lake Country Green German Foam pad
-Polish with Menzerna PO85rd using a Meguiars So1o Finsihing pad

We rewashed the car with a high alkaline soap and wiped the paint down with 91% rubbing alcohol followed by Wurth Prep-Solve to remove any possible oils or fillers form the paints surface and make sure that we achieve true correcton on the paint's surface.





These pictures are after wiping the paint with a solvent, no wax or oil is on the paint's surface to mask the defects. The total correction took 17 man hours which is obviously more than the body shop put into it.

Re: Fixing a bodyshop nightmare

After inspecting all the paint and removing over 99 percent of the defects, we decieded to seal the paint using Pinnacle Souveran, since the owner of the car has some, and we knew it would increase the wetness and depth on this color. It was a great choice.

Re: Fixing a bodyshop nightmare

Gorgeous ! Beautiful work !
Looks like that body shop doesn't bother to clean their pads ! What hacks !

So this is what you mean by "taping off the car" before polishing (LOL) !

Was all polishing done with a rotary ? If so do you step rpms up and down ? What speeds were used ?

Cheers

Re: Fixing a bodyshop nightmare

Awesome turn around! Beginning to really love your work! Body shops sure can mess up paint somethin awful can't they. The worst I've ever seen from a body shop, unfortunately was on my own car. Black paint, left so far from correctly polished that it literally looked like matte black primer. Now, only two years later, the three panels the guy painted are all shedding clearcoat like dead skin in august.
