Headlight Lens Restorer Report

[Snagglefoot]

Cleaned up headlight from 2010 Silverado using 800,1200, and 2000 grit rotary sander, and then polishing compound.

I tried the Turtle Wax Headlight Lens Restorer Kit (about $21) and I must say TW had their chemist's working overtime.

It is a multistep process with a 'clarifier' that uses aluminum oxide as the very mild abrasive as the first step.

Then a lubricant is used with two pads and four sides to remove the oxidation with each pad having two sides for subsequent steps. Then there is a sealer system for the last step.

My lenses were very oxidized and I must say it removed 75-80% of the oxidation and clarified the headlamps considerably. Plan on about 2 hours minimum of intense 'elbow'' grease.

The driver's side headlamp had the worst oxidation, but the interesting thing was that most oxidation on both lenses were located at the upper 1/4 quadrant of the lens.

Use a clay cleaner; can be found in most supermarkets and definitely online. It works wonders and very easy to use

I just used the Cerakote kit on my 2009 CR-V. I’m pretty impressed with the results!

I tried the meguiars ultimate kit on my parents Accord about 9 months ago. It looked great and advertised 18+ months of durability but when I came to visit the other day I noticed portions have already failed, leaving dull spots of bare sanded plastic. I followed the directions and was happy but not so much now. I’m not there to take photos of them right now but on my cars I usually wet sand and spray a 2k clear. That lasts for many years. Or just hit them with a polisher. I keep a cheap HF rotary with a 3” backing plate for headlights and other small stuff. Just did my Camry and it looks good for now. Used meguiars 105 and finished with griots 3 in 1 as a sealant. Next time I’ll probably remove them and clear them.

Sylvania kit, hands down. I had used the Cerakote kit, and while very nice results, the lights got ****ted up again after about a year. I got the cheaper Sylvania kit with steps 1 and 3 only - the activator and the UV sealant only. I had my own wet sand paper. I also used more grades in between the ones that they provide/recommend in the full kit (2x price). My CR-V headlights came out better than new IMO. I keep them protected with some Adam's CS3 regularly.

Yea, I redid my headlights with the Cerakote stuff and they’re starting to haze again. I might go back to sylvania.

Let us know how it goes, I am about to try the Cerakote after a polish.

i did mine with Sylvania - they became less clear after a year and a half for me

With Cerakote I had to start with a courser grit than they supply, and gradually get finer. It took a long time to get it cleaned up. It looked great. But now 2 years later it is not as clear, though still much better than before. So I will use their guarantee and get new material and redo it. They have already sent refinishing pads when the first attempt failed when just using their sandpaper

I used multiple sand papers and then different compound/polish with my Porter Cable polisher I use for the cars. Used a smaller pad. When done I masked off and sprayed with UV resistant clearcoat.

One thing if you have a good clean newer lights or ones you fixed, Headlight protection film helps a lot as it adds UV protection but mostly keeps what you have from getting destroyed by the sand/rock chips that adds to it.

These are original, never garaged on a 230k+ '08 CRV. The headlight film was getting ugly and was glued on hard. PITA getting the glue off.
No before but the foggy is after wet sand.

And reference. 13 year old Sonata, 220k, sitting for many months not washed (engine went). I put the film on when it was new. The hazy you see is actually the small pits in the film from sand/rocks. Never garaged. they did get waxed when I did the car with whatever I was using.

Yup! UV is what caused the polycarbonate to haze over.
