i use turtle wax polishing compound. the white stuff that is pretty mild, little bit of rubbing by hand with a damp cloth and the polish takes em out easy, and is safe for the finish. might want to reapply wax in the area if you have waxed the car.
GS27 will take the scuffs out and won't scratch it( it's a scratch remover), My dad and i own a repo company and when i detail the cars that we are going to sell i take scratches and scuffs out with it then wax over it, although the wax insn't really isn't needed doesn't leave a dull finish. It's good stuff.
