I was at my local Vette parts store, when I saw a C6 with it's clear headlight lens looking pretty dingy... beyond yellow, closer to a golden brown... It was the first time I've ever seen a Vette's lens looking like that... I don't want mine to get that way. Any recommendations or tips to keep the clear lenses looking clear?

Have had my C6 for nearly nine years now. Have done nothing but keep them waxed. They still look new. Sound's like those might be from many automatic car washes and no extra care.

At 94K Highway miles, mine are very badly sand blasted.

I use polishing compound on a high speed buffer to clean them up every so often.
The clear coat which GM puts on the headlight is very durable.
If you saw yellow faded lights, my guess would be that the owner removed the clear coat from the lights.

Good points. Mine does have only 40,000 miles.

Wow, that's interesting.

Everyone seems to think that any sort of polishing will remove the clear coat and cause the plastic to degrade very quickly.

I have polished the crap out of mine, and have yet to remove the clear.

My last car, a G35, the clear came off and they would yellow out in about two months and I had to constantly polish them to keep them clear.

Is the clearcoat used on the headlight cover also used on the transparent top? They both seem to have a rainbow cast in certain light.

I don't have a problem with yellowing lenses, but, there seems to be dust or something on the inside of the lense and dust laying in the interior of the lights. How do you remove that stuff? It looks like it might be a complicated job.

The lens problems seem to be all over the place. Some have had very good luck that their lens remain looking great while others have various problems from dirty inside to crazing, spider cracks.

Seems like batch problems more than anything else as I've seen lens on garage queens turn bad and lens in the Arizona Sun look great.

I've sold over 4000 replacement lens to date and the new ones replaced some really bad ones. The replacement lens are GM OEM so they're no better nor any worst than what would have came on the car originally.

As far as dirt and crap inside check the rubber boots that cover the bulbs on the back side of the assembly. Water and dirt can enter easily if these are loose, off or missing. The under side of the lens can get dirty if you get moisture in them then they dry out leaving a dirty film on the inside surface.

The lens's are coated with something that I suspect is intended to protect against UV degradation of the plastic. Avoid using glass cleaners that contain ammonia and other chemicals that don't mix well with plastics. Just use soap and water to clean. some opf us have experienced crazing, or a spider-webbing of small cracks in the lens, but I can't attribute it to anything in my case.

Your suspicion is correct. Every time I wet sand headlights, My final step is SEM Solaray UV headlight coating. Gives them that final crystal clear pop too.
