I know this is something that has plagued a lot of us...

What did you use to clean them up? I tried the RainX kit. They looked good for a couple days but now they're back funky looking...

I'm also interested in buying a replacement lense if anyone knows who might have one...

 

wetsand with 800, 1000, 1500, and 2000 grit sand paper, polish with rubbing compond, then with wax and this is what my results were

 

After your done using a kit, you have to make sure to seal the lights, otherwise they will do what you described.

 

i didn't use any sealer. did my car (red car pictured above) back in april and are still as clear as when I firrt did them. But then again, I wax them everytime I wash the car so that might help keep them clear

 

There is your answer, wax protects what you did to your lights.

 

^ Yep

Wax Contains UV inhibitors, UV is what damages your Headlight lenses. Meguiars is coming out with a Headlight protector in 2012, cant wait for it.

 

Wahttt... where'd you hear about that? I figured it would have made a blip in the detailing forums by now.

 

What can you use to seal your lights? I wetsanded mine a while back and they looked great but oxidized again, since I don't have time to wash my car/wax my headlights every so often to keep them from oxidizing.
