Thanks Spray. I may go with this 4 pc set and also check out the 3M gun. I don't know much about painting at all since in my collision and auto body class we haven't gotten into the painting process much. Do you know of any good books that would help me a lot on painting? I know a bit on air brushing but not too much at all on painting things like cars. Before I paint my car I am of course going to practice a ton like on my golf cart, some sheet metal, truck fenders, etc because I am picky on paint jobs on cars like seeing drips or orange peel or anything.
