I have polished over 20 rotors and it is quite easy. I remove the rotors and put them on a clamping work bench (sears) and start by sanding them with 220 grit orbital sander. After all factory gring lines are completely gone, I use a 6" polishing wheel on a 1/2" drill and start with BLUE compound and work my way to red. The finish is mirror and perfect. Nice, easy weeknight project. Takes me about 1.5 hrs for each rotor, both sides for laced or spoked wheels, 1 hr for one sided for solid wheels.
