The Om3ga folk have done a quick run down on repairing scratched CDs and come up with a wizard wheeze. When all else fails try hair gel. Yep you heard right, hair gel. So put away all your bomb making equipment and start fixing those disks for the good of democracy, liberty and fraternity.
So I took it upon myself to perform an experiment, to determine the very best way of dealing with a scratched disc. The limit I set myself, though, was that whatever I did it with must be somewhere in my house, and can’t take longer than 5 minutes, including waiting time for things to dry, etc.
