Look at these wheels

[chevy71super]

I bought these wheels from red71cheyenne last fall. They were on a Blazer he bought. I took them home, washed them in an acid wash to get all the crud off. They were in fairly tough shape. Seems like the wet Washington weather allowed moss to grow on them and eat into the aluminum. No kidding. Like a moss on a rock. After I got them cleaned up I sanded them down with medium grit to get most of the nicks, scratches, moss holes, etc off of them. I followed with 220 grit, then 320 and then 400. (I probably should have used about a 600 grit after that.) After sanding I used my die grinder with a buffing pad attached. The one on the left is after the buffing wheel using the most aggressive grit. Next I will use a finer grit followed by Mothers wheel polish. I bet I have more than 6 hours on each wheel so far.
