I did my own a few years ago. Want to get a good compressor (at least a 7hp 175psi w/30gal tank), good HVLP guns and a good airbrush and start doing bikes on the side (racebikes mainly at first for practice). There is a guy around here that dos helmets, HD's and such. Theres a guy who I worked with at Geneva Vans who airbrushes helmets damn good. His names Chris and lives somewhere near Antioch area is all I know. I dont remember his last name though.
