Well I did it, and I don't have pics right now but I will take some tomorrow when the lighting is better.
It worked VERY well, unfortunately from the pictures you wont really be able to tell because a lot of the crap I have happens to be on the INSIDE part of the lens, so I will have to open the headlight and clean it from inside eventually. But pics to come tomorrow!
2000 grit wetsand by hand + 3M Plastic Polish buffed by hand + Meguiars finishing glaze applied by hand.

Hey, those of you guys that have done this. Have your headlights yellowed over time? Supposedly these polycarbonate lenses have a UV coating on the surface. If you sand and buff it...you are obviously removing this layer of coating. Personally I have had no problems so far, but I only had to sand down very little.
And to the previous comments, yes I hand buffed my lenses.
And yes a ton of elbow grease and a few hours, but the lenses turned out nice and shiny

OOOOOO yellowing over time....thats me. After about a month or so they begin to get this hazy yellow glaze on top. Usually after a wash though and intense scrubbing the yellow goes away. Is there a product that i can purchase to remove this. Such as that stock UV coating? Maybe a spray on application?

If I sand the headlights, they might turn yellow in a month...?

It has not happened to mine yet and it's been more than half a year. I usually park my car outside too so it's always being exposed to the sun. Maybe it's because I didn't sand off too much of the coating. The headlights I used for my retrofit weren't too badly pitted so I didn't have to do too much sanding.
Thanks. I'll give it a shot.
How about applying 303 Aerospace protectant on the headlights after sanding? It's supposed to provide good protection agaist UV damage.
