There are several wipe-on-and-buff UV protectants that supposedly reduce yellowing of Lexan lenses. Which product has worked well for you? This product would be used on lenses that have not yet noticeably yellowed, meaning the factory coating is still reasonably intact.

It's one brand of polycarbonate.
 
Megs headlight protectant and Wolfgang Plastik Surface Sealant are just some of your options.

Based on your experience that product is superior to the other options?
 
I would think twice about the Megs Headlight Coating. I applied it last year and it protected the lights for about 10 months before starting to fog up again. Car sits outside in Ohio. Not impressed and will try the Sylvania coating next.

A very good detailer on here recommended C.Quartz DLUX available on autogeek.net. Can also be used on black trim.

After reading all the reviews I could find I conclude that every product ranks anywhere between lousy and terrific. Maybe protective laminate is a better option?

Doesn't it say on the package, the clear only lasts 1 year? And you need to reapply yearly? Is it not a permanent UV repair?

The best methods are either buy new housings or sand/rubbing compound/polish till clear and smooth then use automotive clear coat. None of these miracle wipe on's will last.

The lights are only two months old. Same age as the car. I am not looking for a fix, I am looking for a protectant.
 
I think your best option is to park in your garage as much as possible and pick shaded parking spots. Some of the clearest headlights on older cars here are driven by the elderly who park them in their garages. We may not have to deal with rust in the south, but the sun is brutal to paint, plastics, and rubber seals on cars.

If that's not possible, wax/seal them often and hope for the best. They're supposed to have their own UV coating when new.
 
Of course, new headlight lenses have factory UV coatings on the inside and on the outside. The outside coating will over time come off. That's why an additional layer of protection makes sense. My car is parked inside when possible, which is about 10 hours a day. I think I'll try McKee's 37 Headlight Protectant Spray. In the end it probably doesn't matter. My company will furnish me with a new vehicle in two years. I doubt the headlight lenses will suffer significant UV damage before then.

That will just all wash off with the first rain,and may contribute to dry rot. It'll be no different than using Armor All on them,same results.
 
My Santa Fe's never went yellow or hazy, just used a sealant/wax on them yearly from when it was new.
