Thanks for the input guys. It was black powder coat to begin with and out of boredom I stripped it all away and polished the calliper. I tend to do things like this far too often, it was perfectly fine black. haha Ah well, I'll leave it for now as I got ancy and filled/bled the system.
Cal, there is so much raw alloy on this bike, the polishing ferries are gonna quit. I'm welcoming the oxidization, give it some age.
b.linden, Thanks. I used lock washers and a dab of green loctight. I've done it before and I'll do it again. Never had an issue.
