way to remove scratch from gds help!

[DreamcastKeV]

i was going to the store to buy some scratch remover stuff (quake 3 had a few minor scratches that was stopping me from ripping it) and a guy there said to just use toothpaste as it worked just as well. i tried it and it totally ####ed up my game! the whole thing is just covered with little scratches and the dc wont even play it! Does anyone know any remedies for scratches that work? or a site that sells scratch remover stuff for a cheap price? help would be greatly apopreciated
