Craptacular fog light glass polishing?

DR1665

Might need a translator.
Hope the title got a laugh or two.

I'm considering buying a used foglight for my project car from a guy in New York state. Only trouble is, the outer glass lens is horrible-looking. I realize that polishing glass can lead to surface imprefections which can negatively affect the beam pattern, however this is a flat glass lens which protects a projector lens. The entire assembly is a fog light, so I'm not very concerned with the light being refracted a bit oddly, given it's proximity to a projector.

It looks like typical northeastern United States salt/grime/road scum has taken it's toll for a few years. I can not speak to the feel, as I do not have the light in my possession yet (thus the post, if it's salvageable, I'm buying it). I do have access to a picture of the light, but it is both exceedingly large and I do not have access to my FTP server from this workstation at the office.

I wonder, (maybe you were wondering when I would get to the point? ;)) if any of you might have some good tips for fixing this glass? I was thinking I might bake the assembly, remove the outer glass lens and try the old vinegar/water soak for a day or so, then maybe follow up with an OTC polish from Autozone that I can afford to use liberally to clean it up.

We're talking an ordinarily clear lens that looks like it was found in a cave somewhere.

Any advice is much appreciated. Thank you.
 
there are many good glass polishes that contain cerium oxide. That is whats used for glass polishing. you should do a search on cerium oxide.
