    • We'll see Long Term
We'll see how it holds up to UV rays. Haven't had it long term to know yet but I like McKee products so I am confident it'll be ok. It goes on easily and shines up nice on the headlights

    • Goes a long way!
Seems to work OK. I’m doing all of my lenses on the truck. A little bit goes a long way. I’ll continue to use it every time I get a truck wash.

    • Headlights
I just got my headlights refinished and waited a week or so to apply this product. Time will tell. It was easy to apply x 2 coats.

    • Good for protecting headlights from sun and dirt
This product seems to work well protecting my headlights from yellowing and clouding over from exposure to the elements. I do wish the instructions told how often to apply it. I have used it once this past year.

    • Protect your vehicle's headlight lens from UV damage and yellowing - use this!
This McKee 37 product is polymer based spray you apply to your headlights and taillights after getting your vehicle washed and then wiping off with a clean microfiber cloth. If you consistently follow this practice BEFORE your vehicle lens start looking cloudy and yellowing from outdoor UV damage with age, you'll be pleased with the results. For those that know the history of McKee's, this product is basically the same as the former Diamondite Clear Plastic Liquid Armor product (which is now discontinued). I have been using the former Diamondite and now this McKee 37 UV protection product on my 2007 Saab 9-3 since Day One of ownership and the Saab's lens are just as clear and new looking as my 2019 Jag-g-g XE R-Sport. All my vehicles headlight/taillight lens get the same treatment after each car wash ... six quick precise pump sprays for each lens following by spreading/wiping of a clean microfiber cloth. Similar to cleaning a window with Windex, this McKee product dries shortly after wiping with the microfiber cloth and you're good to go until your next car wash. The McKee product is relatively cheap versus the cost of replacing a pair of headlight lens (if you keep your cars a long time like I do). An 8 oz bottle typically lasts me a whole year protecting three vehicles that get washed at least twice each month. Note, this product only protects EXISTING CLEAR CLEAN LENS. If your headlights are already damaged from UV and age, you can try one of several abrasive Lens Cleaning Kits and then using this product afterwards. Having been down that road on several previous vehicles and vehicles for family members, if you're going to keep the car or have bought a used car that has a lens clouding/yellowing problem, I'd suggest "biting the bullet" and replacing the bad lens with a new clear set of lens outright and then using this product to keep the new lens looking clear and new. Why? A clear lens transmits the light from your headlight bulb or LED matrix the best and the farthest. This gives you the best nighttime vision safety vs driving and trying to see with attenuated light being projected through an old UV damaged cloudy lens. Try this McKee's 37 product, you'll like it! ... show more
