It works great for scuffs will not remove scratches your fingernail hangs on FYI... had a deer propell off my windshield scuffed up with hoves worked great removing didn't remove scratches it helped? But didn't remove totally

I had a few scratches on the windshield of my brand new SUV which just made my OCD go bonkers. The scratches weren’t deep enough for my fingernail to catch it so they were pretty shallow. I tried using automotive rubbing compound using a rotary polisher but it was very slow going with not much difference aside from slightly lightening the scratches. Then I made the colossal mistake of using a YouTube fix where some guy mixed rubbing compound and Orange hand cleaner with pumice and swore up and and down it got rid of scratches on his windshield. Talk about false advertising. I applied the mix per the YouTube instructions and it just caused more and new scratches over the original scratches. F*** me. What did I do???I found this windshield repair kit desperately hoping for a fix without having to turn to a professional. Although, a lot of detail shops just won’t do windshield repairs for some reason. I read the instructions and prepped the car with tape and covering just in case. This product contains cerium oxide mixture which I believe is found in the commercial glass polishes/compounds. Instructions said to use a corded drill due to the requisite RPMs but it’s 2023 and who’s got a corded drill.I started off using a very small amount about the size of a pea with my cordless drill. I only used enough pressure on the drill to hold it flat against the windshield. I started off slowly just to make sure I wasn’t causing any further damage. First go and I did notice some improvement. It says to watch the heat generated since too much heat could cause your windshield to crack. They also recommended using some water if the mixture got to dry and to cool down the windshield. I went through several more reps for about 5 min at a time until the windshield was warm to the touch but not hot. I would wait about 10-15 min in between reps to allow the windshield to cool down. After the first few reps, the scratches started to miraculously fade and after about 8 reps using the mixture, spray water, and moderate pressure the original scratches and the scratches caused by that YouTube tip disappeared completely. The glass was smooth, scratches free and I couldn’t see any remnants of the scratches using a flashlight and shop light at various angles.I was actually worried this wouldn’t work due to the low ratings, but it worked perfectly for and got rid of all the scratches on my new windshield. It took time, patience, and a little elbow grease but this was totally worth the price and effort. I tried taking pictures of the before and after but my iPhone just couldn’t capture the scratches clearly enough to post. YMMV but it worked like a charm for me and saved my brand new windshield.

Works well. The ol lady ran wipers without blades and cut deep grooves in the windshield. Tool a while but it got them out

Originally i had given this four stars - but upon further time to assess the effectiveness, i have to reduce it to two. The product does appear to work because you do reduce some fine scratches, and the windshield becomes clearer as result of it removing not the scratches, in as much as other contaminants on the glass. But when you look at headlights and drive at NIGHT time, you can see that the scratches and swirls for the most part remain, although reduced. This results in distorted oncoming headlights and you get a fuzzy, hazy spread of light sources coming through your windshield. At first i thought this is as good as i can get my 14 yr old windshield, but its distracting and potentially dangerous, and turns out that you CAN do better with something else. And i don't know everyone else, but this is what's important to me and why i'm trying to fix it - night time driving and oncoming lights.While using the felt pad and the cerium oxide solution is the right idea, the mixture of the cerium oxide and the quality and size of the felt pad in this package is incorrect and insufficient to do a good job. The cerium oxide is too fine/weak and the felt pad quality and size is too poor and small to cut enough in to the glass to smooth it out. Yes, if you do it enough eventually it may get there for small areas and scratches perhaps, but I've done my entire windshield twice on two cars, with each session being 1-2 hours, and the distortion and scratches remain. Since this is my first time, i had thought that perhaps i'm not using the drill correctly (not enough or too much rpm or pressure on glass and the kind of motion needed) or not enough of the mixture and water spraying, and it was my technique that was at fault and not the tools at hand.The CORRECT method, if you want to do the entire visible view of the windshield right and not a small scratch, is to get powder cerium oxide and mix that with water, use plenty of it, and use a quality felt pad that is five inches in size, not three. And this is what i did and the results can't be even compared. I spent a lot of time doing this for both of my cars, and if you need to do the entire windshield, do yourself a favor and get the powder and mix it yourself, and use a larger pad, and if possible, a rotary polisher or sander (as for a drill, the larger pad size may make it difficult to keep consistent contact with the glass). You will get lot better polishing and correction, for a lot less time and effort. There is a 8 oz cerium oxide (which will cut more than this solution) that sells on amazon and you can find the 5 inch backing pad and felt pad all for about the same price as this in total. A bit more money spent in trial and error on my end, but I hope this review saves you some time, effort and money.
