Well, I don't know what I would do, but it sounds like the only option is to have the area repainted. Maybe you could take it to a body shop and they could do something to the effect of re-painting just that one side. There is no way you are going to be able to remove the scratch yourself, no wax is that good. By the way, how did you do something that scratched the paint to the metal all the way down the side of the car.
