Okay I'm into the crafts thing and go to craft shops all the time (Micheal's, Hobby Lobby, etc.) and they have those airbrushes. While small they should be big enough for bike frames and parts without a lot of wasteage of paint (plus you can custom mix paint, add catalysts, etc.). This should work pretty well right?

Another thing I found at the craft shops is this stuff used for leafing (as in gold leaf). It comes in lots of colors and paterns on a mylar backing, and is applied by putting down a light, even coat of adhesive pressing down and peeling off the backing leaving the leafing material behind. This stuff would be great for making custom decals that are bright shiney metal colors (gold, silver, bronze, copper), or metalic colors. I've even seen pearlized, and mother of pearl paterns that would look pretty good. Layered aplications can also create drop shadow effects and pinstriping. Of course if you use this stuff your going to need to clear coat over it, but I think maybe I can make some interesting 3d effects by using alternating decal-clearcoat applications (put down drop shadow layer, apply few layers of clear coat apply top layer, clear coat again).

Any thoughts on my ideas?
