Im getting my front and rear calipers powder coated. the fronts are no problem, remove the piston, seals, etc... NO rubber.. i know...

the rears though seem to be a lot more to do. the rear caliper isnt just a piston and a couple rubber seals. i removed the piston and seals.. and then realize that theres 2 rubber o rings inside the caliper.. now ive removed everything from the calipers, and i plan to get them powder coated and then rebuilt. i know everything i have to do ......im simply just looking for anyone who has powder coated there rear calipers to see if they have done the same as me and removed everything from inside the caliper.. thanks!

so anyone with pics and there process is much appreciated.
