Following ... any update? As mentioned before I would love to know how you got rid of the rash ?
Hey sorry I haven't has much time to get on lately. Basic steps were.
Spray entire face of wheel with paint stripper (Rattle can from.Walfart).
Taped off areas i didnt want to scratch.
Then started hitting the worst areas with a metal file by hand. I also took down the parts of the edge without curb rash to try to even the entire outer edge as close as possible.
Once I hit the lowest level of the deepest scratches, I got a less course file, and then eventually on to I think 80 grit sand paper. > 120 > 220 > down to 800 I think and then just started polishing it. That's really all there was to it. I think i can attribute it coming out fairly well due to the fact that I sat there for a good hour or two and just took my time for once. It wasn't a fast process so I'd just take a 5 when my arm started giving out.
I was tempted to use a die grinder at first but the aluminum is too soft for that I thought, so I just had to put what little muscle I had into it and just start filing and sanding and on and on. Eventually got down to 800 grit, then scouring pad, then I used a polishing wheel on a corded drill that I have with some polishing rouge. Started empty the courses down to the finest rouge. Less is more with that stuff. The cordless drill was too slow. It wasn't cutting into the metal so I had to use the corded, but also not on full speed. You can watch and see what's happening. If you get the right speed, you will see the metal start to look hazy but removing the larger scratches. Sorry it's hard to explain. Just need to tinker with it until you get the right setup going.
