3M Quick Headlight Renewal, Helps Remove Light Haziness & Yellowing in Minutes, Hand Application, 39186, 1 Sachet

I need to clear up some misconception about this product based on reviews I’ve read. First, if you are reading this keep reading you will learn exactly what you need to do from an individual with experience with this stuff.You looking at products like this because your headlights are not looking so hot anymore. So what are your options?Option OneIf your headlights are lightly oxidized: I know “oxidized” is not the best word, but what I mean is that basically this kit, “3M 39173 1 Pack Quick Headlight Clear Coat”is an extremely light buffing kit that is the equivalent of using a light rubbing-compound before waxing your car. So, if your headlights are lightly oxidized this kit will likely work. However, I am guessing your headlights are much worse and you are nervous about putting sandpaper on a drill and sanding your expensive headlights. I understand, but do not kid yourself, the 3M 39173 1 Pack Quick Headlight Clear Coat kit works, but its not a miracle product. Hence, I urge you to read Option Two.Option TwoIf your headlights look like my headlights in the “Before” picture attached with this review dull and pitted, the product you need to purchase is “3M 39045 Headlight Renewal Kit with Protectant.” This is a heavy-duty kit that includes the sandpapers to resurface your headlights in three steps using the following sandpapers and wet-sanding pad.• 500-grip sandpaper (heavy duty sanding to smooth out the surface and pits)• 800-grip sandpaper (smooth’s out the scratching from the 500-grit sandpaper)• 3,000-grip wet-sanding pad (smooth’s/removes out the swirls left by the 800- grit sandpaper)• Headlight Clear Coat (final application)The attached picture is my Mini headlight that has 13 years with 165,000+ miles on of wear-and-tear on it, and as a result my headlights were massively dull and pitted. The “Before” picture really does not do it justice to show just how bad they were.Attached Image Break Down• The first image shows the headlight before it was restored. It really does not show how dull and bad the pitting is, but it was really bad.• The second image shows how the headlight looked after sanding with 500-grit sandpaper. There was another sanding step with 800-grip sandpaper, but I do not have an image of that.• The third image shows the headlight after sanding with a 3000-grit wet-sanding pad and then sealing the lens with the protectant.The Restoration Process Is Simple with the kit 3M 39045 Headlight Renewal Kit with Protectant.”1. Clean the headlights with soap and water.2. Tape around the headlight with the included green tape. NOTE: I used additional blue tape because I did not want the sanded plastic to get into my headlight pop-up washers. This is why there are two layers of tape.3. Sand the headlights with 500-grip sandpaper.4. Sand the headlights with 800-grip sandpaper.5. Wet Sand the headlights with 3,000-grip sanding pad.6. Clean the headlights (make sure they are dry), and then seal with the included protectant.There are some good YouTube videos showing you how to use this heavy-duty kit. Just take your time and your headlights will look great again.Tips1. Separate your sandpapers into two stacks. One for each headlight.2. As you are sanding down the headlights, occasionally clean off your sandpaper buffing pads; you can do this by patting them on a towel or something. This will unclog the sandpaper, thus allowing you to work more efficiently. After I was done, I put the sandpaper buffing pads away because I can use them again for one more job.ConclusionI am not trying to sway anyone into buying something you do not need, but after reading a bunch of the reviews here, and knowing my personal experience and aptitude with mechanics, it is obvious that many individuals with negative reviews are not being realistic about what this kit does, and do not want to purchase the correct heavy-duty kit that they really need.To Clarify: Bottom Line1. If your headlights are lightly oxidized use kit “3M 39173 1 Pack Quick Headlight Clear Coat,” and go with Option One.2. If your headlights are dull and/or pitted use the heavy-duty kit “3M 39045 Headlight Renewal Kit with Protectant,” and follow my instruction in Option Two.******* Please let me know if this review was helpful by clicking the “Helpful” button below*******THANK YOU!

so ive bought and used a couple different headlight lens clearing kits, over the years, but not for my cars, i had a couple people that had me detail their vehicles on a regular basis and they had bought these higher priced, more elaborate kits, (ive been shocked at the cost of these,typically they are 20-30 or even higher. but some are meant for heavier clouding/oxidation(?).this kit has been the only one ive found thats under $10 and delivers excellent results, every time, not labor intensive, and only requires your hands and a lil elbow grease.AND ITS FROM A TRUSTED COMPANY 3Mthe instructions are on the back of foil package and are straightforward and easy to understand. and at no point was i sitting there thinking "what did they mean when they said... " etcthe kit contains 3 items 1 circular piece of 3000grit SANDING PAD (not sandpaper) and 2 clear coat wipes,it really took longer to remove headlamp assemblies and reinstall them than it did to do the cleaning and clearing process.i may have gone a bit above and beyond, regarding how i went about this process, as it doesnt require you to completely remove the headlamp assemblies, but when i did this it was summer, and fall victim to heat strokes extremely fast, so i did this inside my apartment over night. so i had a more contolled setting to work in and the headlamps could dry in a contolled setting to merit best as possible results.and i also went ahead and prepped fopr this and went and sourced a full size 3m 3000grit wet/dry SANDING PAD, which can probably be sourced on amzon or at most any autoparts store or on LOWE or in DEPOT (i specify Pad for a reason as there is both paper and pads the pad is what you want .youll immediately know the difference between them just make sure its the same grit as the piece that was included it may be a different color, which doesnt matter.i dont recall if i needed it or not but it was an added peace of mind to have on hand so if needed it i had it.remember that with things like this, its the same rules as painting, to merit best results its all in the prep and process,dont let it scare you, i was a tad wary from the more complex kits, id done prior to this one, and this is on my personal vehicleand the pics i included i hope provide a good visual reference as to how well this kit works.but yeah overall its a awesome product, and i have purchased this 2 more times and done mine, a friends and my moms truck, and all have came out consistent and amazin! highly recommend!anyways i followed direct

I use this product first on a 2007 Ultima and it worked great. The headlights went from very cloudy to almost perfectly clear. It works so well that I then tried it on a 1999 Subaru and had similar results. It went from pretty cloudy too very clear. Being that happy with it then decided to tackle the headlights on a newer BMW. At the start, these weren’t terribly cloudy, but definitely had some wear on them and I figured why not see if this product improved them. Unfortunately, the product seems to have made them quite a bit worse. Almost as if the rubbing compound didn’t work. They look like they did after I first sanded them, so I’m not sure why the rubbing compound didn’t make them clear as with the other two cars. So I’m not sure what to think, perhaps there are different kinds of plastic on headlights? Anyway, they made the first two cars look great which was really what I bought the product for so I’m not entirely disappointed in it.
