GLASS POLISH DIY 3” Windshield Polishing Kit for Car Glass Restoration, Remove Wiper Blade Damage, Fine Scratches, Haziness, and Water Spots, Restore Glass Clarity and Shine - GP21005

I don't often write reviews and I cannot compare this product to others, but I had to write about this one because I am so happy with the results!I have an older car. We moved to a house on a dirt road several years ago. My side window became scratched due to dirt and the up and down motion of the window. The window was so scratched I had to roll it down to see out of it (yes, even in the rain). I just finished using this product and I am amazed. The scratches, which were fairly deep, are gone!Best.Product.Ever.

I tried Clay Bar, Polish and even toothpaste and none was able to remove wiper blade scratches. I just got this stuff in the mail today, read the directions. Used a 18v Rubi Cordless drill and BAM.....All completely gone in less than 10-15 min max with a few breaks along the way. This stuff is magic and I love it!!!

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

The bottle was busted when received and there was no damage to the box it came in. Saw no improvement to the windshield and after buffing and then cleaning with glass cleaner, it left a film on the glass. So I now get to spend time cleaning it off. DO NOT PURCHASE!

I had a small section of scratches from 0 grade steel wool on my windshield. Not deep enough to catch a fingernail on but deep enough that a couple passes with this stuff didn’t touch it. I resorted to my 5” buffer and cutting pad then I sanded with 2500 and 3000 grit which seemed to help a little. As a last resort I used a ton of the product and made 15-20 more passes. Though it did help a tiny bit, it didn’t 100% get rid of the scratches. I think I would have to do a lot of sanding to get rid of it entirely. That said, it did buff out my 2500-3000 grit sandpaper marks, so that’s a plus. I probably wouldn’t buy this product again.

This is an AWESOME product! I got it to use on a very noticeable, long and deep scratch on the glass front of a curio cabinet. This is NOT a strong or reinforced type of glass that the product is designed for, so I was very nervous about trying it. One of my fears was that the area I worked on would end up looking clouded, micro-scratched, or otherwise different from the untouched areas of the glass. Given that the scratch stood out like a sore thumb in all lighting conditions, is right at eye level, and the cabinet is lit from the inside, I figured I had nothing to lose and at worst I'd have to replace the glass anyway - so I gave it a try, not expecting much. I dared not follow the instructions for using a mechanical buffer due to the fragility of the thin glass, so I did everything very gently by hand (using a piece of soft cotton tee shirt to apply the paste), and I assumed it would therefore be a slow process. To my surprise and delight, in short order this product worked like magic! The area i worked on is just a clear and smooth as all the rest, and the scratch has effectively disappeared. Because the scratch was so deep, it is technically still there if i get close and really look for it, but IT IS NOT NOTICEABLE AT ALL, no matter the lighting conditions. For the sake of this review, I wish I had taken a "before" photo. There's no point in talking an "after" photo, because it would just show a piece of unmarked glass. This product so greatly exceeded my hopes and expectations that I'd give it ten stars out of five if that were an option.

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.
