so i am changing my brakes this weekend, on my 00 ss i was just woundering about sanding my rotors where there are rusted and painting them.? is this possible.? and the calipers aswell i know these can be done. in college and have no money so sloted and drilled out of range. if i did have money i wanna go fast. lol. i think this can be done and was woundering what u all thought i have some spare rotors of a 99 trans am i was going to try on them. if it is possible what paint would u use.

thanks in advance.
