Query: Did not work for me yet

I tried it on a DVD with a quite deep scratch, several times with a few drops each time. It didn't work. For shallower scratches, I used the SkipDr motorized thingy with good results, so I haven't tried this yet. It'll probably work, but I bought this hoping it'll fix the deeper ones. I'll rate it as "Fair" for now.Update: I finally tried it on a shallow scratch. Didn't work. Several rounds in the SkipDr didn't fix it either. I then tried buffing the scratch with toothpaste, another round in SkipDr and everything's ok. So don't waste your money on this compound. Toothpaste and some serious buffing will take care of all but the deepest ones.
