Polishing out Side Window Scratches?

[Katfish]

I'm in, is the eBay shot above the way to go?

Same.  It's cheap enough and I have nothing to lose.  I'll need replacement glass either way if I can't clean it up.

I bought a kit years ago, possibly from Eastwood, the kit has the correct pad and cerium oxide so nothing real wrong with it but it won`t really remove scratches - just polish it.. Anything more than very minor scuffs need to be sanded with ultra fine paper first.
