Auto glass is different than plate glass.
Windshield: Laminated glass.
This is two thin pieces of glass with a plastic lamination between then to make "safety glass".
Although it is two pieces of glass the impact resistance is only that of one single glass sheet.
Side windows and back-glass: Tempered Glass.
This is glass that is first heated and bent to shape then "tempered" in an oven.
The impact strength can be up to 6 times that of regular plate glass.
When Tempered glass breaks it shatters into small (approx 1/4") crystal sections.
Windshield:
Small (fine) scratches can be removed with CarPro Glass Rayon Polishing Pad and Ceriglass.
Ceriglass is based on Cerium Oxide which is the polish that is used to finish glass beveling.
Side windows and back-glass:
Tempered glass reacts different to heat (polishing) and can "explode" when being polished.
Be very careful when polishing tempered glass. always make sure the glass does not overheat.
