Headlight lens restoration -- who's done it, what works well?

(yes, I did search the site, but most of the posts were older... )

Still busy with other things on the Envoy right now, but both it and the Accord's headlamp lenses are cloudy. The Sierra's aren't, but that's because it has new ones (due to breakage of the molded plastic in the back of them... I'm on set #3, already (long story))

Anyway... who's done this in the last couple of years,
what did you use,
and did you like the result?
(optionally, how long has it lasted)

I don't care about cost, as much as I do ease of application, and good looking results. So don't be hesitant to recommend something pricey, even though most of you know I'm a cheap-azz, when possible :twocents: I've got two cars to do, and the Envoy will be the test bed.

If you're not recommending a 'kit', then please do list all materials needed (brand of toothpaste, w/ different grits of sandpaper, etc.)

Don't need long descriptions of the 'how-to' (I'll research that part)... just recommendations of what (or, what 'not') to use.

Thanks in advance for the feedback!

I used the McGuires restoration kit. Comes with a disc to "polish" the lens, the cleaners, and a spray can of clear. There's enough for about 3 cleanings.
Lasts about a year or 18 mos.

For the Envoy, I would just replace them. They are cheap to replace, and the truck will look so much better. I tried to restore them, it didnt last. Like 4 months.

Edit: They were cheap... They have nearly doubled in price since I replaced mine 18 months ago. 130 bucks for a pair now, when I paid 70.

Dont know what year and model your Honda is to see what they go for.

The big thing, for any of the kits, is a finishing UV ClearCoat. because you are effectively sanding it off. Without that clear coat, all road debris and grime, will just stick to the plastic, and your back to square one.

The 2 videos I used for my attempts..

Edit: RA is going to be about the same cost after shipping and taxes as evilbay.
The evilbay Kit I bought.

I did a polish on my 2007 LT lights a few years back with auto body polishing supplies I had leftover from my Jeep project. I machine wet sanded from 1000 to 2500 and polished with a 7 inch foam pad with polishing compound. After that I just polished out a good coat of car wax and it held up fine for the last year I owned it. I'm not so sure I'd use any clear coat from a spray can as those are usually lacquer based and themselves are prone to 'yellowing' and 'crazing' with time......especially if you apply it with a heavy hand.

I used the 3m kit. Worked well enough.

My two cents is to go with new ones. They look great and since we all know what will eventually happen put some UV protectant on them from the beginning.

I had terrible scratching from the 3M kit following the directions. I've used Mothers and Maguires kits with good results.

For protecting them, I've seen and use 3M UV film. Used that on the Caprice and so far has stood up well after a couple of years but it's in storage during winters. Buying a new set is impossible on this one. One problem though was the compound curves they have and getting the film flat was a bitch. I should do the Sierra and the TB while they are still looking good.

I tried a different method. I used a sodium hydroxide oven cleaner saturated rag that removed the yellowing. Over half an hour I periodically rubbed the surface until all the yellowing was gone. Then I polished the surface with a foam pad and polishing compound.
And finally I sprayed it with nason select clear.
The results were quite impressive considering the headlights were twenty years old. There was still some fine internal cracking of the plastic which was only visible with the lights on..

Here's how it looked before:

And after:

I had oven cleaner and polishing compound on the shelf. And some leftover clear coat too.
so the net cost was zero - the way I like it :celebrate:
If I didn't have the clearcoat I would have tried the headlight protection film from fleabay......
These are the original twenty year old headlights made in the UK.

Because there are no replacement headlights available for Bravadas, I've had to restore my headlights by wet sanding with 400 grit until the protective coating is gone and then spraying an automotive urethane clear coat. They came out looking brand new and have held up for five years now and still look great. ~BOB
