That could be normal wear and tear, or GM had a problem with that particular color for that year. Hard to say. I do know that I have seen this fixed by body shops by simply color coat sanding and respraying it with clear--I've had it done, but not for the same reason. The clear coat is a special paint with a flexible additive added or it is special for the bumpers only. There are 4 different kinds of paint sprayed on the exterior of all Firebirds and Camaros--for the front and rear caps (bumpers), the front fenders, the steel parts and the doors. Most people and body shops don't know that.
I spoke to my son about this problem and he agrees with the above . The flex additive in the clear coat allows the plastic bumpers to deteriorate faster than the steel parts of the car, ( hood, rear quarters, etc)... This is caused by mostly U.V. rays from direct sunlight., making it very important to apply a good coat of wax twice a year to protect the finish. This said the damage allready done, he recommends colorsanding as mentioned above, and especially since its a black car, do a repaint (spot job) on bumper and a new coat of clear. Wait for paint to cure, at least 1 month and wax. Hope this helps. Dave
