In your opinion what are the pros and cons powder coating steel wheels vs just using a real good wheel paint based on experience?
Powder coating is way more durable, but also very particular. You need a NON FOOD COOKING OVEN to bake it in (350 deg for 20 minutes), so check Craig for a cheap oven you can park on your OUTSIDE patio.
The material must be very clean. Sand blast the entire rim, then clean it real good with some Eastwood PRE and you should be ready to coat and bake.
If I were you, experiment with a usless piece of steel to get the feel of the process before you do your final product.
Harbor Freight has an el'cheapo PC gun setup, but I really think Eastwood's Hot Shot PC setup is a lot better, although it does cost more.
Eastwood also carries all the PC powders you may want, look for ones that take a bit of heat, since being right at the brakes, some heat will be there.
