Back bumper paint problem
2 Answers
I cannot tell from the photo. If these are scratches you may need to paint the bumper. Have a car detail guy look at it.
Looks like you got "tagged" by someone pulling into a parking space while you were away from the car. If you don't see any deformation of the bumper cover I would try to buff the section with some rubbing compound and then apply some wax or sealer on the area before you took it to a shop to fix.
