Painting a brake rotor

Opinions welcomed.

I plan on having my brake rotors surfaced. I was also thinking of painting the interior part after sandblasting. It would seem that Sandblasting would be best before surfacing. I'm wondering if I should also paint the buggers including the holes/slots so that the machine shop can just clean the surfaces and get a cute effect. I would use Por-15 of course.

Anybody do this before and any gatcha comments.

wouldn't your brake pads wear off the paint extremely fast?

Most of the paint would come off on the milling machine.

Basically this is an issue of doing the sandblasting prep before the machine work, and then

a.) deciding to paint (while the surface is free of grease) and then machine or
b.) machine and cleanup the grease, mask and paint afterward.

The primary benefit of doing the painting before hand would be you ca paint all the little drilled slots with say black or gold (without masking) and then when the rotor is machined it will true the surface but stay away from the slots.

The mounting surfaces will still have to be masked before of after. Could go either way; I will ask the machinist if he minds if he has to grind off some paint to get to the metal?

Mine didn't need resufacing, but I would think it would be better to get them resurfaced first, then mask and paint. The rear (at least on my rotors) has a gap between the painted part and the pad surface... don't know if you wanted that to be painted or not. Painting the slots sounds like alot of work and I don't know if you would actually be able to tell very well that they had been painted? It might still be better to do that afterward.
