I've spent a few hours researching the archives and could still use some help.
I painted my 60 GMC stepside with black PPG acrylic lacquer about 10 years ago over the well sanded original paint. This was my daily driver for years and the finish has deteriorated and is badly chipped needing a repaint. This is a hobby car that (now) sits in the garage most of the time protected from the elements. I realize the best plan would be to strip everything and start over with urethane, but Iím retired with back and knee problems and Iím just not up for disassembling the entire truck again to get all the lacquer off.
Iíd like to sand off most of the easily accessed paint and spray the exterior and jambs with single stage hardened acrylic enamel (black again) to avoid the rub out process of another lacquer job.
Question Ėis there any 2k primer surfacer that can be used over the lacquer where the chips require repair. I donít want to ever use lacquer primer again due to the shrinkage, gassing, etc. In the jambs where the paint is good, does it seem likely catalyzed acrylic enamel could be sprayed directly over the existing finish, or would it also tend to lift the lacquer.
If my only option is to do a complete repaint with lacquer, is there any 2k primer I can use to avoid using lacquer primer.
