I just spend 3 hours sanding one of my 85 vettes rims down with 800 grade sandpaper it looks like crap. I was told that I needed to sand down the rim before i put on polish . . . is it looking like crap because i havent sanded it enough or did i just ruin my rim ? since its down to the bare alum can I just apply some kind of clear coat ? any sugestions to saving my rim ?
