I rattle-canned a frame once. All the advice here holds true. One thing I would add is to be careful about clearcoat. The one I sprayed stripped an amazing looking gloss gold and black paint job. And yes, I used the same paint - both enamel. I don't know if the Clear coat was labeled wrong or what, but definitely be careful. The paint was great but now it is cracked and chips easily. Good Luck!
