Didn't have any luck with that. But I did buy a JFJ Easy Pro Disc Buffer off of Amazon and it worked really well for me. It quit working 8 years after I had it but that's because I used it a lot and I was always buying used DVD's and than buffing the scratches and scrapes out of them. Than they'd work like new. Trust me. It is well worth the investment. But DO NOT use it on a Bluray. It will tear those up.Have you ever (successfully) used toothpaste or some other trick (or product designed for the purpose) to get scratched discs working?
Maybe you could try this: Instructables highlights a simple tip for making CDs and DVDs with scratches readable again. Simply take a cotton ball and dip it in some rubbing alcohol to clean the area near the scratch. Then apply Vaseline or Petroleum Jelly to the disc. The Vaseline will fill in the scratch, hopefully making it readable again.I gave toothpaste a try with one more disc, but there's no notable effect.
