I reviewed the link you gave me and decided to try it out. I knew once I did, there was no turning back. I love the purple wheels but i would have settled for spraying them black if it did not work out. So I tried it out on a small spot and I am amazed! I took 400, 800 and 1000 grit wet paper, sanded a small area, took "Mothers" Metal and Wheel polish, polished it out, then Mequires sealer wax over the area, then wiped clean. Here is my result. OH YEA!
