Polishing Glass?

The driver's side door window on my '65 Val is scratched to @#$%^&. :-?

Is it possible to polish it out? I tried some paint poling compound but that wouldn't touch it (didn't really think it would.)

Is there any difference in the passenger's and driver's side glass? I'm thinking they'd be the same on the '66 down cars, since they're flat.

Thanks!
