So much for quality control.
I'd get the dealership to discount the car enough to what it would cost a good auto body shop to fix it (say $500 to $750?). You could then take it to a body shop and have the area repainted. But personally, I'd consider it the car's first scratch (as they all get them sooner or later and more).
Whatever you do, don't let the dealer attempt to fix it there or by someone of their choosing as they'll do so as cheap as possible and later it will look worse (I had that happen with my first new car).
