General Removing microscratches or scratches from window glass

[MotoLojo]

On my 1970 Fiat 500F, the rear window has quite a few microscratches on the surface of the glass. Does anyone know of a process to get remove them (outside of replacing the glass) that have worked well? I've heard of varying rubbing compounds but not sure of the ideal formula for creating a great surface. Thanks in advance for your help!

You can polish the glass with Cerium oxide and a standard polishing mashine.
