Hi Mike - Be careful of anyone who advertises on Craig's list in our area that says they are mobile scratch repair. I had a couple of guys come out last fall and totally rip me off of $200. They made the scuff mark on my back bumper worse and clearly had no idea what they were doing except ripping people off.
I had the entire bumper repainted at Sterling Auto body and they did an excellent job matching the paint. I should have know there isn't an "easy" way.
