Ah, yes. Carry on sir. Depending on the severity of the scrate (sub p for t), varying the sandpaper will work. For a light scuffing, some 400 grit will work, followed by some 1200 or 1600 grit wet sandpaper. Follow with a buffing.

The only reason I would be apprehensive about sanding the face is that if you got a little too aggressive in spots, it could make the face uneven.
