Just a scratch
The bumper on this Hyundai Sonata was scratched up in a minor parking lot bump. The owner was lucky, if you can call someone backing into you car lucky, in that the bumper was only scratched and therefore didn’t have to be replaced.
We sanded the scuffed place to smooth it out, put three or four coats of primer on it so we could sand it smoother still, and painted the whole kit and caboodle to match the car.
After the bumper had dried to the touch, we set it out in the sun so natures own heat lamp could finish drying the paint.
Well, why not? Bumpers like to sun bathe too.
