Anyone know for sure? I guy I know has a `79 Trans Am that he bought new and hadn't had it long when it received some damage to the LR quarter, which was repaired. He still has the car and the damage is deteriorating and he wants to get it fixed. Other than that the car has the original paint and he seems to think it's laquer. I could be wrong, of course, because it has been at least 25 years since I've used laquer, maybe more, but it doesn't look like laquer to me so I am wondering what year GM switched to using basecoat/clearcoat? Thanks in advance.
