I have powdered coated lots of items using a cheap harbor freight gun and a leftover electric oven I picked up for 25 dollars. I personally would tape off where the spinner nut goes and where the wheel sits against the rotor. Powder coating can add more thickness than paint. You would probably have to clean the coating out of the pin holes to get the wheel on if not taped off. Be sure and remove the tape before baking unless you use tape for powder coating. I just use regular masking tape and remove it before baking or carefully wipe –clean the powder off. I plan on doing the centers my wheels with Eastwoods blasted aluminum.
