I'm interested in trying to paint my junk with okay grade automotive paint. I know very little about doing a good job with automotive paint and am looking for tips / steps. The first vehicle I'm thinking about painting is my trail rig 77K5. It has dents and a little rust where I have drug rocks across the sides / back. I'm not worried greatly about body work and stuff, I just want a decent solid color on the old girl. My other ride is just a 94 Toyota Tercel that I dont like the current mint green color. Straight body no rust. I also have access to okay spray equipment so I think I have that part covered. So here are my questions. 1) Where can I get automotive grade paint. I've looked around and found www.eastwoodco.com / "House of Kolor" paint. Does anybody know about the quality of this paint. Looks pretty good from reading about it. 2) prep work for vehicle #1 (trail abused 77K5) It has some rust and multi colored paint right now (white and blue). I'm assuming i'll need to sand either down to the metal or down to it's original primer before painting on top of it so the multi colors dont show through the final paint. Right? And as for the little rust on there, take that to the metal and prime it before painting? 3)prep work vehicle # 2 (mint green Tercel no rust) Can I just wet sand this vehicle and paint over the old mint green paint? or do I need to take all the paint off down to the primer before spaying it? Also, plastic bumpers.... just wet sand those too and then paint? Or dose plastic require different steps to paint. 4) top coat.... I know nothing about top coats. How many coats? What should I look for? ... Links would be good if sombody knows of some good ones. Thanks for any help rendered.
