I've been wanting to get my R90's painted black for some time now. I'm a little concerned about taking the wheels apart with the one time use bolts. What would be my best option considering I want the bolts black as well:

Should I sand and paint the wheels without taking them apart like my S-lights? Should I get the wheels powdercoated without taking the wheels apart (will the heat damage the bolts and make them unsafe? Should I pay 150 a wheel for the local wheel repair place to do everything for me?

Again I want the rims, center piece, and the bolts all black (semi gloss or flat)
Any advice would be appreciated. I'll start this project when my tires need to be changed.
