I just called my paint supply house and they have a different set up the doing the spray cans like the used to do. This is some kind of a jar system that you can put any paint in and reuse it. Making sure the surface is prepared is the main step in any paint work. I asked about painting engines with automotive paint and he told me that he does do it all the time and the only problem areas are where the heat comes off the heads to the manifolds/headers. He said that he sand blasts the engine parts, primers and then paints. I don't like the idea of paint coming off so I think I will buy high temp paint and have it tinted to the correct color.
