Default Repairing pitted glass headlights

I bought a set of '94 glass headlights that I'm planning on modding, but they are pretty pitted. I've seen lots of writeups about how to sand the lexan's, but haven't seen much mention of glass.

Has anyone had any luck at repairing the pitting for the glass lenses? I've seen some topics on Youtube related to Cerium Polishing, but again, didn't know if anyone had any better suggestions.

Also, has anyone used plastic-x with success on Glass?

^Glass headlights aren't tempered.

Trust me I have looked into "refinishing" glass headlights... but haven't found a sure fire method. And I threw away the two broken lenses that I had. Plastic-x won't work for crap. I tried some compound that didn't do crap either.

I figured if anyone knew what to do April would! ; )

That's dissapointing.

I don't want to sound stupid, but can you sand glass with a 2000 grit and then try a polishing compound?

The compound I tried get 400 grit marks out... and it didn't do anything for the pits. It's little chunks of glass that have been chipped out, the only way you will make that go away is grinding down the surface, and 2000 grit isn't going to cut it.

I don't know anything about polishing glass, but I know it's not like paint/plastic/or metal.

Try looking up refinish a glass coffee table top, hell now I'm going to do some googling.

Holy crap batman, I don't know how I didn't find this thread before. But in the end, I probably still wouldn't do it for the ones I sell because of the amount of time and labor involved. And my luck, I would probably break the lens.

That is a nice write-up--I wasn't planning on spending 6 hours sanding...

I'm going to call around to a few glass places tomorrow and see what they recommend. I'll keep everyone posted!
