Way to repair cracked discs?

I just got the copy of MVC2 I bought off of ebay. The thing works, but it has a small crack radiating from the center of the disc to the thin ring that separates this section from the data area.

The seller was wiser than I was, and clearly advertised the fact that he would accept no returns on the auction page. At the time, I figured he did this because he was sick of dealing with whiners, and not duping people into buying system destroying discs.

Is there a way to reliably repair such cracks, so that the disc doesn’t explode in the drive, or should I shitcan the disc and move on with my life?

as long as the foil on top doesnt fuck up
you should be fine

i strongly assume
