need glass deep scratch restoration tips.

I used a paste made from Cerium Oxide and water I mixed the Cerium Oxide into a paste with a very little bit of water and then cleaned the window before I applied the paste to the glass. I used a small wax applicator pad to slowly buff out the scratches. It turned out really good. i am not sure of how it would work on deep scratches but it's worth a shot. Cerium oxide is a polish used by jewelers to polish fine stones. Link to thread with pictures:
