This product is really more of a polish than a scratch remover. If you can feel the scratch by running your fingernail across it, this product will not remove it. You will need something more abrasive like fine emery or 400 grit sand paper. Once the scratch is flatten, though, Polywatch will give it a smooth, shiny finish. It's kind of pricey and I think you could probably find a big bottle of rubbing compound at a hardware store.
