Good disc repair system

[ShadowBlade]

Is there a good, working system for repairing scratches on a disc? Specifically an Xbox 360 game? This scratch might be pretty deep and I think 360 games are dual-layer discs if that matters. Any help would be appreciated.

Skip DR if you can still find them.
