I used the G2 epoxy paint kit. I got black as I didn't want such a contrast between the caliper and wheel. Also it ties in with my "dark" theme quite nicely I only applied two coats, but could have done several more as there is a generous amount of paint in the can! You can't "save it for later" since you add a hardener to the paint and only have a 4-6 hour window to use it. Due to limited garage space, I could only do one end of the car at a time. From start to finish (wheels off to back on), it took about two hours to prep and paint.
