they are not powdercoated. I threw a fit to BMF about the "krylon paint job" on them. scratches and pitting were bad. They are simply sprayed with what they claim to be "professional grade automotive paint" They do not warranty from "normal driving conditions" only manufacturers defects. Since is is automotive paint yes you can wax. If i wouldnt have sold my duramax i was going to have my BMF's powdercoated eventually
