Re: Polishing Motorcycle Wheels
If there's no rust, the discs are stainless. You do them pretty much the same as aluminum, but they are much harder metal so longer time is required. Good news is, being flat you can use a palm sander or similar and keep them nice and flat. After 320, I go to a sisal/black wheel, then spiral/black, then either white or green on a spiral.
I usually sand off any coatings with my first passes.
I've seen a lot of guys who polish the whole disc, but to me it's silly to do the braking surface itself...the pads will give that area their own finish no matter what you do. And if you go into that area while polishing, it's no big deal since the pads rubbing will even things out.
