I've have one of those hand turned scratch repair do-dads and it works, but as mentioned, it does leave the disc looking cloudy. I'm a little "superstitious", so any favorite disc so repaired would probably get replaced eventually. I have some concerns about the long term viability of a repaired disc. The sound doesn't seem to be affected, but I worry that the abrasive action on the whole disc surface could cause it to fail prematurely. Of course, only time will tell.
