my wheels are scratched and wanted to get them refinished. I would like to do black with the outer ring and bolts that line that silver. does anyone know, are those bolts just decorative or do they come out. and is the outer ring removable?
the guy at the powder coat shop told me that if they came apart and he could do them individually he would charge me $100 per wheel. if he had to tape it off and coat twice it would be $175 each.
