I am looking for paint so I can paint part of my brake assemblys on my 2001 Mustang. What kind of paint should I use? Should I use primer first on my brake calipers before using the color I want? Also I am trying to but my headlights and my third brake light. The plastic has been scratched so bad that I am sanding it before I buff and polish it. I would like to use a drill gun to buff and polish. But I dont know if they work fast enough to get the job done. I have a 1200 RPM drill but it doesnt seem to go fast enough. Any suggestions....my budget on a drill gun is about $100.00. If not I will just buy the parts brand new instead. Thank you in advance.
