Glass Polish
 

Has anyone ever heard of a glass polish called "Z-12?" It's supposed to remove even light scratches, so I would guess "sand blasting" on headlight lenses as well.

Here's their link:

I use the stuff from these folks http://griotsgarage.com I have used the finer of the two the sell. On one of my cars, someone had put a plastic cling sticker on the inside of the rear windscreen, could not remove without destroying what part of the defrost worked. Above polish does not remove water spots.
