I could not stand my dirty wheels, the clear coat was cracked and comming off so i took 2 fine wire wheels and took all the clear coat off then used 1200 wet dry sand paper then polished the surface with mothers aluminum polish on a 4" auto buffing pad in my drill. Then put a good coat of wax on them. took about 2 hours for the front wheel. I will keep them clean as the po did not!!
