I used it with a Meguiars sponge. Gently and without much effort, two minutes per headlight. I leave the result to the pictures you see. When I find time, I will do the headlights with a DA polisher and PlastX, and then I will also apply some wax. Personally, I find it an excellent product and easy to use. On the S2000 soft top film it didn't do miracles but improved it by about 80%, I would say. It now has no cloudy spots or yellowing

It does what it promises. However, you need to do it several times and for quite a while for better results. I used it to remove scratches from the dashboard (plexiglass) of my car

Very good product, if the headlight has not completely fogged up, it restores it quickly and easily. After that, it needs the corresponding protective ointment to be maintained.

I got it for restoring the plastic window in a convertible. It improved it but not by much. On the headlights (without much wear), it does a very good job of cleaning and polishing.

Instead of the new one as shown in the photo, they sent the old version which is less effective...

A friend gave it to me and I decided to try it, 15 minutes by hand on each headlight, this is the result!
You can see how yellow the left headlight was
And how the right headlight turned out afterwards.

Good evening, gentlemen. First of all, let's clarify that the product will not restore yellow headlights as mentioned by a friend above, but only prevent oxidation. So if you are in the advanced stage, DO NOT expect any results. Having tried several products from the company and having a fair but amateur experience in headlight restoration myself, I decided to try this product as well! The reason I purchased it was to test its effectiveness in removing small to large scratches from motorcycle headlights, as mine is very difficult to remove and polish. However, I saw that it did NOT work on the plastic, so I decided to try it on something it was specifically designed for, but still NO results. Below, I present a headlight that I simply passed with a polishing compound and K2 UltraCut, and next to it another one that I struggled to polish with Plast-X. The conclusions are up to you..

It actually does what it promises. I was skeptical and pleasantly surprised. The photos I'm sharing don't do justice to the result. I saw a big difference.

I bought it to test and see if it works!! Without using sandpaper!! And using it by hand on a cloth, it's true that it requires a lot of work, but in the end, when you wipe it, you can see the difference! The truth is, I would buy it again and it doesn't require a lot of quantity!! I did 4 headlights in total with 1/4 of the package!
It would be good to apply a special protective coating after using this cream to prevent them from yellowing again due to the sun!! Personally, I bought one from the same brand and I was satisfied!

I tried it with a buffer... in headlights with a serious problem, you can see a big difference... but in headlights that need a little, meaning for detail, it didn't do the job... while with sandpaper, I brought it to a good level... I don't know... at least I didn't succeed... while with another cheap product unrelated to headlights (wax), I did waxing on the car and it was a professional job... I expected the headlights to also be done, but they didn't...

It does what it promises, like every Meguiar's product. Used on a 5-year-old car as well as a 20-year-old one, it cleaned them like new.

You should know that if your headlights are in bad condition, they need to be first sanded with a p1000 water sandpaper, then with 2000 and 3000. AFTER that, apply the polish with a sponge or a microfiber towel (although it would be ideal to have a polishing machine). And of course, don't let it dry... as soon as you finish applying the polish, clean off the "extra" with a clean cloth. I did it this way and together with the headlight protectant from the same company, I am very satisfied... it's worth every euro

It really does the job... The truth is that I didn't expect it... with a little patience, the lights are in much better condition...

I happened to purchase and use it after cleaning it in a good - theoretically - car wash. The owner thought it appropriate to clean the transparent glass of the instrument panel with a random cloth, leaving scratches and spider webs.
I tried three times with the corresponding pad (yellow sponge) from the same company. While the damage seemed small (superficial scratches and spider webs), it reached a satisfactory level, where I left it (meaning, no one could discern that something imperceptible still existed).
However, after a day, I found that any trace of scratches/spider webs had been completely eliminated. It sounds strange, so I considered that the material requires some time to fully take effect. If anyone had a similar (paranormal) experience, it would be good to share it with us.

I used the product with a soft cloth and rubbed the headlights in circular motions.
On the first application, the surface was rough, but already from the second application, it had smoothed out and the headlights had returned to a very satisfactory condition. I believe it is worth its money as the bottle will provide many more maintenance sessions.
Finally, I would like to add that the headlights were noticeably yellowed, but not in a completely terrible condition.

I used it to remove scratches from acrylic piano black trims that literally get scratched even from dust.
I am very satisfied with the job it did. It almost eliminated all the scratches (it is impossible to achieve 100% on such surfaces) and even minimized some deeper ones.
It is quite weak and requires several passes, but at least this way the risk of causing damage is reduced.
I used pads that attach to a drill. By hand, there is no hope for much.

I tried it on my father's 12-year-old car, whose plastic headlights had started to yellow. I rubbed it quite a bit and it really cleaned them! Not to a perfect degree, as there are other specialized products for that, but it did a decent job. Combined with the headlight protectant, the result was very good.

Amazing product, it removed the plastic from the headlights of an old car in just a few seconds! It was also used on the plastic cover of the odometer, which had many small scratches (spiderweb), and it did a very good job, almost like new!

The ultimate solution to prevent damage. If your headlight turns into a yellow cloth, you will need a workshop, polishing, and reapplication of the protective film. End of story. I tried this product at the beginning of the appearance of the "burning" of the headlight, with a size larger than a 2 euro coin. The seller told me it was quite bad, nevertheless, with 6-7 repetitions using gentle circular motions with a Microfiber cloth, the mark was completely removed. And this comes from someone who is very picky about these things. I don't know the duration of the result (I will update), but along with this, I also bought the UV radiation protection cream from the same packaging. I will regularly add protection creams and wax to maintain its beauty as much as possible. No pain, no gain, my friends... Don't let things deteriorate. They can't be fixed with creams afterwards. It requires polishing, effort, and obviously a professional.
