I have historically used the Meguiar’s headlight restoration kit and have been very happy with it. However, the Meguiar’s kit is all hand sanding (a workout), so I wanted to try the 3M kit because it accommodates drill sanding and wanted to see if it could outperform the Meguiar’s. The 3M kit has a 4.5-star rating with 15,884 reviews, so I thought what the heck.
The bottom line is that I simply could not get a good result with the 3M kit. In fact, I had to use the Meguiar’s kit to repair the poor result of the 3M kit. That’s what the images portray: Meguiar’s repair of the 3M result.
The 3M kit starts with a 500-grit followed by 800-grit dry rotary sand, followed by a 3000-grit rotary wet sand. Then, a rotary polishing with a sponge. I should have paid attention to my instinct telling me that dry sanding with 500 was too deep because I think that’s one of the flaws of the 3M kit. Although I salvaged the poor result with Meguiar’s kit, there is still a haze that was not there before. Frankly, I was pretty upset about the 3M outcome.
The Meguiar’s kit starts with 1000-grit hand wet sand followed by 3000-grit, then rotary polishing using a cloth wheel that is superior to the 3M device IMO.
