I used one of those headlight restoration kit

[Carson Dyle]

I started another thread in this forum on the same subject last year, and ended up using Meguiar's PlastX and was amazed at the results from very little work. I did my headlights in mid-December and need to do them again, which I plan on getting to this week.

Meguiar's is now selling the sealant from their two-step kit, which can be had for under $10 at Walmart or Amazon. I'll seal mine this time around and see how long it lasts.

I also tried their two-step.... the one with the scrub pads then a spray on clear coat. Depending on how much scrubbing you do, it will haze again. My car parked away of the sun (garaged, parking structure) took 2 years to begin to rehaze, a friend's always parked in the sun and outside we used the leftovers on began to rehaze after months, but he treats his car like crap. Both cars are early 2000's.

PlastX works great and is less aggressive. I just used it a few days ago on soft plastic radio/AC displays and was AMAZED. It took a decent 15 minutes of scrubbing and am beyond happy. The plastic is glossy and clear again. I could continue to scrub another 15 minutes to get rid of deeper remaining scratches, but I learned my lesson with the headlights. Just get it up to enough so that light can pass again. I didn't bother to get it to scratch free perfection.

I've removed headlight haze on a few cars with plain toothpaste (no additives)

That and a terry cloth seem to have just the right amount of abrasiveness to get the haze off fairly quick.

It must have been a very light case. I tried Toothpaste, 3M rubbing compound, Baking soda and it didn't even make a dent.

Then I tried some PlastX and it started coming right off instantly. It still required to some elbow grease to get to decent clarity, but it was 100x better than using toothpaste.

I would start with PlastX, and if that fails then go for one of the sanding solutions...
