My front bumper needs the bottom black part repainted. In a couple areas its no longer black but a off grey which bothers me. So I was wondering whats the best way to do this? Should I remove bumper or tape? Is there any specific paint I should use? Any pointers I appreciate!

 

Try using Plasti-DIp, it is a very tough rubber coating. Just tape off your bumper, no need to remove.

 

Plastidip FTW!
