Any real owners from 86-87 posting in this thread?
Okay paint delamination was mainly limited to the blue and silver cars. It was in the formula. Everyone bought paint from the same supplier, therefore every one had the same prioblem. Silver had the most metallic content of any paint so add in years of heat from the sun and that color would fade faster than any other. And look at your cowl tag! You will see that GM only used Laquer paint on your G-Body. No enamels,no base coat/clear coat and no water based crap. The word Laquer is stamped there plain as day!
As far as GN's go the big problems were.....
OrangePeel
Solvent evaporation. Spider webbing in other words.
Paint contamination. The black was supposed to be solid but metal particles from the paint equipment gave certain parts of the cars a metallic look. Not heavy but you could see the flakes if you looked.
Dealers usually did a poor job of fixing the problem because GM only paid a certain amount for time and materials. Kind of hard to get a body shop motivated in doing even a half azzed job when they were getting paid half of what it really takes to do a good job.
I never did figure out why some GN owners tried to have their crappy paint matched when something happened to their car.
Owned quite a few Black GM cars. Every one had sub standard paint.

These are only the black cars that I either bought brand spanking new or were a fairly new trade in. So I know somebody else didn't screw them up. I've always said if you didn't buy it new than how the heck do you know what happened to your car?
