I found a product that has worked on a few of my CD's. It's called the Bona Fida Perma-Spin Skip Fixer. It's made in Canada by Exclumen CD Tech. It is a pink liquid that seems to have the consistency of liquid car wax (it wouldn't surprise me if that's exactly what it is). I had a few CD's that were scratched and I was able to restore most of them to their original state.I went to their Website and it lists a few products. I clicked on the Perma-Spin one and it didn't work for me, but there is contact info there. I bought mine in a used CD store.
