I would recommend not using it even for light scratches. One a scratch is a scratch you can not remove or repair it. That is a fact anyone proclaiming such claims is saying without facts. You best to make a 1:1 backup of the original and just use your backup cds. A deep scratch will never be fix and also such a scratch renders your cds or dvds a coaster media.
