Headlight Lens Restoration

One headlight on my recently acquired car is 11 years old, the other is 1 year old. The older one appears to have a cataract, so I bought a 3M Headlight Restoration kit and got into the renewal. When I finished the project yesterday I was very satisfied with the result and stopped for the day.

Today I looked at the lens in a different light and noticed faint but obvious swirl marks on the entire lens surface. I re-did the last several steps of the process, (a) 3000 grit buffing pad and (b) the final polishing compound. I compounded the lens twice. All the swirls were still visible when viewed at specific angles.

I guessed the polishing compound to be the culprit, that it might be a bit aggressive. I drove to Autozone and purchased a Meguiars product, http://www.meguiars.com/en/professio...-remover-16oz/ . That bottle of very fine polish compound did the trick. All swirls gone and the overall finish was much glossier.

I chose this product from Meguiar's. Don't know if its the best. Their text states it will last for 1 year.

Much too soon. I've owned the car for just 5 months, and bought it with the lens in its deteriorated condition. Previous owners probably had the car parked in the sun quite a bit.

I have a garage and now the car is parked in the garage 24/7. I drive it maybe once a week. It may be many years before I'll see the need for a re-do.

Instead of using a sealer, canít you just use a LaminX film over your lenses?

Not sure about LaminX, but I have Headlight Armor and it has about the same life span as the bare lenses, but replacing it is a lot harder than doing the old sand and buff.

The best headlight restoration kit I've ever used has to be the Meguiar's Heavy Duty Headlight Restoration Kit. Comes with all you need, except a drill of course. Highly recommend it

How bad was the condition of your headlights?

As bad as this?

Good to know. I used the Meguiar's but the "not so heavy duty" version. It did a good job and it was by hand. I'll try this one and use a drill this time. Thanks!

No worries! I can stand by that kit. It's great! Did my buddy's headlights. One kit can do 3-5 sets of headlights.
