So, I just got my CS40s fixed after my wreck, and I'm looking at putting them on my new GT/CS.

I've gotten 3 of them clean, and to this point my method has been water, scrub, clay, polish, wax.

The problem is, a while back, I had a brake issue, and it ended up with flakes of metal melted into my clearcoat (like tiny particles) which then rusted. I've worked them hard and gotten the rust off of most of the shiny parts of the wheel, but it is still on the interior, and there are small amounts still on the visible parts of the wheel. Now, I'm assuming this is rust, but the majority of it is probably melted in break dust.

My question is, what methods should I use to get the stuff off? Right now I'm hitting it hard with a clay bar and it's coming off, but not fully, and it takes forever, because there is so much of it. The wheel looks good enough to just throw on and go, but I want to make sure I'm not going to regret it in the future, as well as I am a perfectionist and I want it back to mint condition. I just don't see it as worth it, the way it looks now, to sand the clearcoat off, and then recoat, because that is a ton of work and it looks pretty good as is.

Also, when making recommendations, keep in mind this is a CS40 black, so parts of the wheel are painted black. This makes it even more difficult because I can't just go to town with sandpaper, or I'll scratch the paint off.

Any ideas would be appreciated. And yes, I know it was dumb to let this happen, but what is done is done, and now I have to try to make the best of it.

 

Bump for help. I have the other 3 wheels on the car, but I haven't put this one on yet. It looks like it may be showing signs of pitting as well, from where the clearcoat was breached...but it's hard to tell. I guess I'll just throw it on and run it by the tire shop when I get a chance and see what they have to say. The claybar is working, but I could do it for weeks and not get it all off.
