Let me know when you get it done, and how it turned out. I been wanting to do this for awhile, either paint or powder coat!

If you have a choice, don't use sand or glass beads (they're essentially the same thing). Use plastic media, nut shells, or even nickel slag, but using sand could result in a disaster if any of it gets inside the caliper. It's very, very difficult to keep it out. I've done quite a bit of this stuff, and you can't beat plastic media for removing the paint without damaging anything.

Thanks for the advice!!! Would sanding them by hand as opposed to sand blasting cause issues?
