its easy to do it yourself...most thing to remember is to tape everything off...from body pannels to break rotor and other hoses that are near by.
Go to Pep Boys and buy high temp break caliper paint the one i used was VHT something like that. Then use light thin coats and wait like 10 min between each. go until you get the right color depth
I would go with clear coat on top since it will prevent from paint chipping and will look better.
