Im sure the 83 is only a cleaner/polisher, what you want is something that will remove the scratch. For that I would try Meguairs Scratch X 2.0, its about $10 bucks, I have used it with a buffer, and it removes very fine scratches and swirls effectively.Your local auto store like Advance, AutoZone, or Napa Auto should carry it. But Heres a website that has it:
