I know most of our cars have this, guess they just yellow a tad from all the sun exposure because of the headlight design? Mine aren't too unclear, a few spots look a little "foggy" like condensation but under the lense without a leak if that makes sense....What have you guys done to update your lenses? From what I researched you can't just buy the lense ONLY which and than you could just bake it off and replace....so is there any other remedy? I have a guy local who paints the housings, installs LEDS all that stuff, but with a subpar lense not sure if that's worth it......Would a vinyl overlay look any good? Not the dark, real tinted ones, but something to cover up portions of it? Most of my issue lies in the upper part of the lense and the side by the amber sidemarker. Thanks.

 

Definitely not most of our cars, my cars been in Texas and Missouri all its life so if sun were the main cause, mine would be completely hazed. The G35 maybe but not the 37. Your best bet is to try different things in stages. First try just cleaning them really really well. If that doesn't work, get some plastic swirl polish and buff the crap out of them. If that doesn't work, you'll need to do some wet sanding and then treat them with a good amount of wax. If that doesn't work, replace them completely. You can find a cheaper set of headlights online with broken tabs or missing ballasts etc and take the lenses.

 

I just buffed my 08 headlight lense for the 1st time about 2 weeks ago. They were not to hazed, I would say they still looked 65% good but i wanted to refresh their look. I used some PlastiX and a porter cable. They came out pretty good. I prob will refresh them a couple more time when needed before i give them the wet sand treatment. I wet sanded my 02 BMW 7series a few years ago and they came out beautiful so i suggest you do that if yours are really bad.

 

You wouldn't happen to have some before and after pics? Or just before pics to see if ours looked similiar prior to you doing this...Mins isn't that bad, I just want to get them right before I invest $700 in the lights. Thanks in advance.

 

I've heard of a 3M clear seal, maybe do that after its been polished?

 

There are several headlight lens renewal products advertised on TV. Probably can find something at Autozone or similar.

 

Getting them clear isn't the problem, keeping them clear afterwards is. You have to seal them correctly or they'll be yellow in months.

 

I'm sorry I don't but here's a link to a diy restoration.

This product works well and should be easy to find, blue magic is the brand if you can't see that.

 

I have used the 3m headlight restoration kits with sandpaper and polish and the drill attachment with good luck on my wife's van. I would recommend doing that. If you follow the instructions the lenses will look like new when you are finished. the last kit I used came with a sealant to use on them afterward. I would just remember to wax them regularly after doing it to make sure they don't get hazy again.


Also, be sure you tape off the painted areas around your lights because it's easy to touch a spot with the sandpaper and leave a mark.

 

I had a detailer polish them with a compound, and then reseal with a Quarts UK sealant product.

 

Thanks for all the replies guys, much appreciated. I just got a headlight restoration kit and it looks pretty damn good. I'd say 90% vs a brand new lense. That's good enough for me. It was misleading looking at them, they did look oxidized but they looked more "cloudy" and I thought it was from a possible leak and condensation getting in and making the inside look like that....Well the compound with the few diff grits of pads that came with it got rid of all that real quick, came with a sealant, I'll stick with that I guess or I guess I could do Blue Magic in conjunction with that...But yeah know I can focus on getting my housings painted and the iron man halo installed. Thanks again.

 

Please use 3M headlight restore kit. Used it last week and my headlights look brand new!

 

I did the restoration on my brother's car using the "Wipe New" kit but for mine, I used the "Spar Urethane+Mineral Spirit" finish method. Gotta agree with those who swear by the "Spar Urethane+Mineral Spirit" method. Headlights look brand new.

 

If you're in the DC area, I recommend Clear My Headlights (http:\\ClearMyHeadlights.com).

The previously foggy and yellow headlights in my 2008 G37 now look brand new, and it only cost $75.
