I chose to do this with the wheel and tire mounted. So, don't
get in a hurry.
You have to be very careful. I used a 1" artist brush for greater control.
I used Aircraft Paint stripper and a stainless steel bowl. Applying only a small section at a time.
As you can see in the picture below, I applied stripper only to the face.
I did not apply over the lip, as not to get any on the tire and only up to the machined edge.
Once it bubbled up; less than a minute. I would remove the
paint with a paint scraper.
I did not use any force as not to actually scrape the aluminum.
I would come back with paper towels to wipe it clean.
I used a plastic scraper for stubborn areas and to cut up against the machined edge.
I borrowed one from the kitchen that we use to clean the pizza stone with.
Don't tell the wife, she doesn't know.
Once done, I washed the wheels down with soap and water.
I found the front wheel would not strip as easy as the rear.
I don't know why, it just didn't seem to react to the stripper as well.
Once it was dry I polished the wheels with Blue Magic Metal
I used a small buffing wheel on my drill. The center stand came in real handy.
