I noticed a very small part of the front bumper is likely scratched. It is underneath the car and you cannot see it unless you crawl down from the angle with your head almost touching the groud. It's like some scratch on hard plastic, feels rough, but doesn't seem to be very deep. I guess it's a scratch on the coat. Though it's only for a very tiny area and underneath the car, I was wondering if there's anything I can do to protect this area. Thanks a lot.
