This is a straight out serious question from me to you guys that if doable...in the long run will save you time, and money and have much better end results.
I ask you all this:
When you decide to paint your brake calipers, what are your goals for when your finished?
Meaning...what made you decide to do it?
Why did you choose that color?
Are you after having the caliper show up better through the rim both standing still and moving?
If there is anything else you care to add in, feel free to. I have a very nice idea I think many of the D.I.Y.'ers might like. The end result will be paint able, and powder coat able, polished, or even left nude.
