Thanks for the responses and after rattle can painting a set of car wheels and pricing various rattle can solutions I'm leaning toward Spray Max 2k rattle cans of epoxy primer, color and clear from 66autocolor.com. I might include a sandable primer too, not sure.

Those who prefer enamel from rattle cans, where do you find interesting colors? Unfortunately I'm only finding basic colors in enamel.

Thanks again.
