I found this site AutomotiveTouchUp.com that claims factory matched paint (about $20) a friend of mine uses. There are also some excellent touch up kits available for about $25. I used to do body work years ago...today it is a total rip-off.

6 inch of bumper rubber roughed the surface (caused 2 about 3 inch not thru paint scratches that caught finger nail)of my door below the handle $650. When I aeked...we have to disassemble the door and remove both quarter panels to blend the paint,. BULL DOODLE!!!! $30 of touch up and good buffing (hour labor is appropiate. Shouldn't cost over $100.
