Removing paint without harming the original finish on a brake caliper

I'm a bonehead or blind; you pick

I used some duplicolor brush on caliper paint on my rotor hats to get rid of the rusty look. I accidentally dragged the brush against the brake caliper which has some sort of black finish. This is on a new touareg (yes it's a TDI)

The black finish may be powder coat, I'm not sure, and I'd like to remove that caliper paint. It's been on there for 2 weeks; I just never noticed it.

Any ideas before I get at it with a bit of fine sandpaper?

I don't think I'd use sandpaper. You might try some mineral spirits or turpentine first. The problem is that the calipers get hot which means the paint not only has dried but, most likely, cured (and quite well, at that). You may be in for a frustrating series of events.

see above . . . . .. . .

powder coating IS tough stuff, but many things that remove paint will also remove powder coating . . . or try hard enough to fubar up the finish.

it MAY be possible to ease the point of a razor knife or exacto blade between the paint and poweder coat and pop it off . . . . I will likely try that first

Polishing compound - won't do anything to the original finish but make it shinier, but it more abrasive than you might think.

If it took you two weeks to notice, is it really worth removing?

Sorry if I sound stupid but what about brake fluid...?

The caliper finish most be inmune to it but the new paint will fall right off..

I know... Blind or dumb, or maybe both..


I was actually able to remove the paint. You know when they say prep is the most important step, well for once that worked in my favor...i was able to chip the paint off with a plastic scraper. There is only one part of the caliper where is didn't come off perfectly, thats where is isn't machined. Not too bad afterall.

Thanks for the suggestions.
