Cleaning aluminum slots

i took mine and used some 600 grit sandpaper and wet sanded them down took out the scuffs. Once that was done and i was satisfied with the scratches i took mothers and pollished the He!! out of them by hand. It took about five full polishes by hand but they look pretty damn good if i do say so myself ill try to take pics tomorrow during the day. I also painted the back and taped the fronts off to paint the slot part satin black after i polished them. The only better way i can think of is to have the sent out and polished up but i didnt want to spend any money on them i did all four wheels for about 10 bucks. P.S. The only reason i tried wet sanding them is because they were junk if they wouldnt have cleaned up they were sitting on a car in a field for 10 years and they were ugly. I had always wondered if my idea of sanding would work but didnt want to try it on nice wheels so i tried them on these and it worked great. Ill post pics tomorrow. Justin
