so any way, here's what I did
1. I taped the wheels off to expose only the clear coated area.
I also removed the wheel weights. I did not remove the wheel from the car or the tire from the rim however if youreally wanted to go nuts it would make it easier. I didn't have the time and I did not want to pay for mounting and balancing to take the tires off of the rims
2. then I took paint stripper put that on left it for a few minutes it crackles and eats at the clear coat its pretty cool.
3. after that I started with 80 grit sand paper, to get the rest of the corrosion off, then after I got it all evened out I used 400 grit
then 800 grit than 1600 grit then steel wool.
4. after that got the mothers aluminum polish out and hand polished for a few minutes and it looks like new again.
It takes about an hour a wheel, I think total time was about 5 hours.
You can repaint the clear coat on the wheel, so you won't have to polish frequently. I prefer to polish once a month over the crappy clear coat.
