I discovered to my dismay that my car has a shallow 'bump' on the roof, like a football may have landed there at some point. The bump is completely even with no edges or creases. It looks like it could just be pulled out with no necessary surface treatment. But is the such a tool for the job? Or does such a service exist?
I tried banging with my fist on the ceiling from inside the car, but the roof is much stronger than I imagined.
