Wow....and WOW again?. Those paint jobs are awesome Bruce and so are those model builds!! Your skills being a professional auto body painter certainly reflect (no pun intended there) in the quality. I'd say, the majority here use model paints (air brushed or rattle canned) with some use of craft acrylic even and more of a hobby grade air brush. And there are some here that do great paint jobs with it.
My painting skills leave a lot to be desired and my modeling skills in general are far from that of a lot of the guys' on this forum but heck, I just keep plugging away.
