I recently bought a grille on ebay for my dads 68 Satellite (same grille as 68 Roadrunner.) When I recieved the grille it was in much worse shape than what I was expecting from the pictures and discription. There are several scratches on the grille, some fairly deep. I asked a couple of buddies and they say to try to use sand paper to try to get the scratches out. Anyone ever try this? The buyer will not take the grille back so I need to try to make this one work if possible. Thanks.
