I had my 73 Buick Riviera repainted 3+ years ago. Within a few weeks the paint around the sideview mirrors began to lift in a ripple or wrinkle as if the mirrors were installed and pushed into soft paint. The same problem developed around other areas such as door lock cylinders, body moldings(wheel, trunk lid, doors and rear window). The paint is now hard and brittle and has chipped off of one rippled area. The owner of the shop said he has never seen this problem before. After doing a little researc h at the store where the paint was purchased it was suggested that the paint might be too thick. The car was painted without stripping(at my request and with the owners agreement)and has had two previous repaints which the shop was aware of. They are now saying the problem is due to too much paint (thickness) on the car. Being a car owner and not a paint expert I am looking for information, suggestions, knowledge of similar problems or other causes of this condition. I have been trying to resolve this with the shop owner in an amicable manner for several years and have just been put off and stalled. All moldings, door handles, etc. were removed prior to body work, prep and paint. PPG Basecoat Clearcoat was used to paint car. Responses appreciated.
maxriv73 1st off welcome to the CC forum. Prep is everything in a paint job. It sounds almost like the paint lifting form not painting quick enough between coats & the paint flashed so you no longer have the proper adhesion between coats, if you don't get the next coat on in the proper time the paint will some times wrinkle & lift in time or just peel off. The other possible thought is that the surface below the new paint wasn't sealed properly & was not compatible with the new paint on top & caused lifting. Different style/blends paints are subject to that type of thing. I'm not a pro-painter by any means, but I have seen & heard of those kind of issues in the past. Just my thoughts. Good luck. Budnicks

I would say it probably was not sanded and cleaned properly in those areas or the paint may have been applied too thick to quick.

Sounds like theres lacquer underneath the 2nd repaint, and everywhere it was sanded through, the lacquer was exposed. Probably was not covered with a suitable thickness of primer to isolate the lacquer job. So the simple answer is yes the paint is too thick. Not applied too thick, but built up too thick. The person who decided it was OK to put fresh paint over an unknown thickness of an existing finish is the mistake maker. There are paint thickness guages for avoiding these situations. To fix, strip and re-apply.
Well i guessed wrong, i was thinking that it wasn't the right primer/sealer that caused it. Safe to say now thats why i didn't say anything... Learned something new! Seems the owner of the shop should have been aware of this being a shop that does this work. IMO..
I have had similar problems... the answer i have found is that it is due to 1 or more of the following. Improper hardener, surface to cold when sprayed and "piling" the paint on when it was sprayed. I have also heard that "fanning" will cause it too. but i'm no expert
