Stole this from a friend.
Paul Argyropoulos Just saw a video on the Forum yesterday that seems incredibly quick, easy and effective. Use Mothers Mag polishing compound. Looks easy, quick and very effective. Do a search and take a look at it. it's worth a try before you set off and do anything else. A forum member also used it and confirmed it worked great.

 

There is also a video out there where he cleans it with Windex, swipes it once with acetone and is done. He 'says' that lasts 6 months if car is left out in the sun.
I HAVE NOT tried this myself, can't bring myself to experiment on a $650 headlight

 

I tried this on my son’s 2005 Pontiac Vibe. It’s his winter car and we had nothing to lose. 3 minutes later and they looked like new. Careful when polishing at high speed. The lenses are plastic and it’s easy to damage them with high speed polisher

 

I saw a video where the final step was to spray the headlight with a Rustoleum Clear Coat product that had UV protection. Person said the headlight would never yellow again!

 

Here's the Clear Coat product used in the video:

 

Saw several video's on using mothers mag and alum. polish. This seems like a great fix for the headlight problem. One video, however, said "do NOT use a paint type product on the lens after polishing". He recommended using a product called "303 UV protectant" or "McGuires headlight UV protectant". Said it, the protectant, lasts about a year before it has to be re-applied. Let me know if any of you have tried this approach.

I tried Brasso at one time, on another Chrysler and it looked fine for about a month, then it looked rough again in short order.
I think all these products just polish the rough edges of the hazing. To get a good job you have to expose virgin plastic under the hazing and this means the use of one of the kits or supplies like those in the kits.

 

I use mothers when polishing plastic, metal and everything in between. Great polish, used it on my headlights and its still looking great, Woody

 

How bad were they to start?

 

I tried Mother's Mag & Aluminum Polish on my wife's 2006 VW New Beetle's headlights and both of them turned our looking near new. And the VW Beetle is famous for having "cloudy" headlights. I was favorably impressed with how easy it was to use the Mother's product. And will continue to use this technique if the headlights ever get really "cloudy" in the future.

I have always used Meguiar's PlastX Clear Plastic Cleaner & Polish on my XFire's headlights & taillights. But I've done this service every 6 months ever since I've owned the car. And the headlights still look like new. I never allowed them to get "cloudy".

 

Be careful of polishing to deep, especially if you do it a couple of times. I used a buffing pad on a drill on other cars and a year or two later the plastic cracked. To bad they stopped using glass!
