There are do-it-yourself powder coating kits available. I didn't do a search on it yet, but the product I saw was featured on an automotive show on Spike TV. It was a good showcase, too. I didn't realize that powder coating was actually powdered plastic sprayed on, then held on temporarily with static electricity, and finaly permanently melted on in an oven. Basically a plastic "paint". The guys in marketing were on the ball when they decided to call it "powder coating"! You have a great idea. If you don't find it, let me know and I'll tell you what I find.
