I'm getting ready to start some painting soon and was wondering what to use. I wanted to get a high fill primer on the frame, axles and grill and then paint them as well as the engine and control arms all the same color. My neighbor used to do a lot of painting and he said that if you add a couple of tubes of hardener to Tremclad rust paint it gives a bulletproof finish. Any comments on this? Any suggestions of what kind of paint and primer to use? I've painted choppers and airplanes before but never a car so easier is better and I don't want to have to do this again.

Thanks,
Sean
