I almost exclusively use Dupli Color...it is worth the couple extra bucks, esp. when doing a low budget "spray" job, the quality of both the paint and the cans seem to be a little better than any other brand I've found. For a low budget paint thru a gun, Rustoleum seems to be great, quality and gloss, durability, etc., is awesome for the price, roughly $20 a gallon, but their spray cans suck.
