Meguiar's Two Step Headlight Restoration Kit, Headlight Cleaner Restores Clear Car Plastic and Protects from Re-Oxidation, Includes Headlight Coating and Cleaning Solution - 4 Count (1 Pack)

I used Meguiar's Two Step Headlight Restoration on my car’s foggy headlights, and overall, it made a noticeable difference. The kit is easy to use, and I liked that it didn’t require any power tools—just some elbow grease. The cleaner did a good job of removing oxidation, and the second step (the coating) helped restore clarity and added a nice protective layer.That said, if your headlights are severely oxidized, it does take some effort to get the best results. It’s not an instant fix, but if you follow the directions and put in the work, it definitely improves headlight clarity. For the price, it’s a great alternative to more expensive restoration options.

This stuff worked so well and so easily that I feel obligated to review it. I used a different product last year. It took quite a lot of time (about 2+ hours) and work to clean the plastic and then buff it back to something like a clear, glossy-ish surface that the headlight could shine through. It didn't really look good, the headlights were not very bright, and they yellowed again within six months.I picked this Meguiars product for my second try because of the protector solution, which appeared to do two things I wanted: a) it fills in the sanding scratches on the plastic lens and makes it shiny and transparent again without any buffing or polishing b) it will prevent the lens from yellowing again so quickly.I was totally right about the first one. You basically sand off the lens with one pad and the cleaning solution, taking off the yellow layer of the plastic and leaving it white, almost bluish, but totally obscured with fine scratches. Then you spray on the protector and the scratches get filled in, leaving the lens looking clear, like slightly wavy glass. It achieved this very well, and easily. Total time less than one hour, including waiting between coats. Didn't even have to rub very hard.I don't yet know about the second one. Too early to tell, it's only been 4 days. The protector has cured, the headlights look very clear, and they are definitely throwing more light on the road in front of me. I will just have to watch and see if they yellow. I will probably ask the manufacturer if it would help to refresh the protector periodically.In sum, I am very pleased with it, both ease of application and great results. I will try to remember to update this review after 6 months or a year, once I know something about the longevity of the application.

...it's not some miracle worker. The lenses will never be 'as new' as it became abundantly obvious in the end, despite all the care and effort I tried to implement when using this Meguiar's restoration kit. Try as hard and with as much care as I did, there was still some residual haze left over, though I must say that the lens covers looked MUCH better than the sorry hazed-over state that they had been in. While easy-to-use and apply in concept, a fair amount of elbow grease is a given with this solution, enough so that it had me thinking that a refinishing kit that requires the use of a power tool might have proven to be a more effective and efficient choice. But I must say that I was still quite pleased with the end result, as was my wife (the subject vehicle was her car, after all).No the headlamps don't look factory-new after the Meguiar's treatment. The yellowing is gone but the lenses are not crystal-clear as they once were all those years ago when the car was new and unused. But they do look far clearer than where they had been and the LED lighting that emanates from this Mazda's 13 year-old lamps haven't been this bright and clear in years. And of course it's far cheaper to revitalize the headlamp housings than to spring for all-new units, which by the way aren't particularly to install as a DIYer given how much of the car has to be taken apart in order to get the old headlamps out and the new ones in. Modern car designs do sometimes suck at times.It was worth the couple or so hours I spent scouring the lenses and masking the lights to prevent overspray of the clear spray coating that finishes the treatment. Despite not having a "perfect" end result, it's still good enough to merit 5 stars.

Worked exactly as advertised. The oxidation came right off, and the final coating kept them from fogging up again. Great value and a noticeable difference in nighttime visibility. Definitely recommend before replacing expensive headlights!
