I'll second what Ron says on the paint that Jim Carter sells. It sprays well straight out of the can. I suppose you could easily use it in one of those sprayers that uses a can of propellant instead of a paint gun. However, I did have an issue with it matching on my interior however, as it was noticeably darker than the original hidden spots on my interior. I was able to have it adjusted by the local paint shop, and it came out close enough, since I'm painting everything.
If you had the formula, a paint shop could mix it and put it in a spray can for you for less than $40. If you have the original part, they have books of paint chips you could match it with visually and that would give them the formula.
