I have a question about painting a car. The original paint on my '74 is lacquer. I have been prepping the car for paint for almost a year on the weekends or spare time. Sanding and sanding and of course more sanding.
I have talk to a few people about painting over the lacquer paint and I have a few different answers. One of the problems I am concerned with is the "lifting" of the old lacquer paint. I am aware that stripping the car of all the old paint is the best way to avoid the lifting problem. However, I don't have the resources to strip the whole car. I am using a polyester feather fill on the car before I prime and paint the car. Is the poly fill an appropriate way to seal off the lacquer from the primer and paint?
Stripping is alway best, but if the laquer is still in good shape, that is, no checking, spiderwebbing ,especially on bumpers.. it shouldn t be a problem .. what are you going to use as topcoat? Urethanes?
Yes. Base coat clear coat. I was told using the poly feather fill would isolate the lacquer. That way when I apply the primer it would not interact with the lacquer paint. All materials are from Sherwin Williams.
Not to oversimplify the answer to your question, but it's safe to put enamel over lacquer, but never lacquer over enamel. Now days there are so many types of paints available, I think if I were you I'd do a test panel before shooting the whole thing. Also, the guys at the paint store are your best bet for the correct answers.
