DIY 3” (75mm) Windshield Polishing Kit for Car Glass Restoration, Remove Wiper Blade Damage, Fine Scratches, Haziness, and Water Spots, Restore Glass Clarity and Shine

Did exactly what I thought it would! My story... I tried Aquapel on my new Audi. This is a flourinated polymer that chemically bonds to the glass and makes water bead like crazy. The application went fine but whenever it would rain and I'd use my wipers at night, the windshield would almost completely haze over as the wipers passed by. It was difficult to see and the wipers seemed to chatter all the time even with new blades. So I went about the process to remove it -- not as easy as you'd think. The company indicated to use Bon Ami cleanser to scrub it off/weaken/remove it. So I used it by hand in a fashion similar to how you would buff out scratches with a swirl remover. It certainly weakened/removed it and the wipers worked much better. All seemed great that first day but that night driving I noticed swirl marks from the removal process all over the entire windshield when there were oncoming headlights! I had a mini heart attack I swear. :) So I set about to try and polish them out -- I've corrected paint many times. I tried Griots with a glass polishing pad and drill and it made a *very* tiny difference but the swirls were still there. You really couldn't even feel them so I knew I should be able to polish them out. Next, I tried this kit... it worked! I mean, it was a lot of work and I worked each section probably two or three times -- cleaning off between -- with each section getting worked back and forth, up and down, sprayed countless times until I figured the product was broken down enough. I want to say it took about 2 hours to do my entire SUV windshield. It absolutely removed the swirl marks though! There were some slightly deeper scratches from the wiper blade paths -- Audi is notorious for having a "soft" windshield -- and it didn't do much for those but I didn't really care since those will happen anyway. Finally though, the Aquapel that didn't work for me is gone and my windshield is swirl-free again! In hindsight I could probably have just skipped the Bon Ami and gone right to this glass polish kit to remove Aquapel. Oh well... at least now I've got experience polishing my windshield should I ever need to again! I noticed that on my bottle it says the paste contains cerium oxide with 1.5 micron particles and not 2.5 like in the product photo label. Not sure if they changed the mixture to be more gentle and "oops" proof at some point. I feel like to remove wiper scuffs though it's going to take a *lot* of work or maybe their heavier grade product to get them out. TIPS: Absolutely mask off part of your hood, leading edge of roof, and A pillars. Try and seal up the area down below your windshield where the wipers protrude. Don't use a TON of water. Just keep it misted enough to keep the pad spinning freely. All that extra water/compound flinging off the pad is wasted material and not necessary. My drill maxed out at 1500 RPM too and that was a good speed to get great results with less fling. I kept the clutch set at 3 so I wouldn't have to worry about pressing too hard and generating too much heat. My windshield never even got very hot to the touch. Use distilled water. The hard minerals in some water could be enough to actually create *more* swirl marks as you're polishing.

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.

Failure of an off-side windshield wiper blade resulted in an arc of light scratches on the glass of my concours-winning collector car. Ranging from almost-undetectable to 'can just feel them under my fingernail' the scratches caught the light and weren't going to pass muster at my next car show. Not looking forward to sourcing a new windshield for a 50+ years old vehicle, I decided to give this product a try - what did I have to lose? The kit was straightforward, with clear, simple instructions. Taking guidance from other reviews, I kept a spray-bottle of water at hand and went to work. After twenty minutes, roughly 60% of the scratches had disappeared. At forty-five minutes, I had removed 80% of abrasions, with the remaining 20% barely visible - you have to bob-and-weave in direct sun to spot the remaining marks. I plan to take another run at these when my cordless drill's batteries recharge and some feeling comes back into my hand. A few other thoughts: cover everything within four feet of the windshield with towels - the polishing compound, water, and spinning drill are a potent combination. Too, mark the scratches from inside the windshield with a grease pencil or tape to keep on target. Finally, consider giving the entire windshield the once-over when you've finished with your scratches - finishing up, I was confronted with a passenger side that looked nearly new, and a driver's side that was dull. This is a great product, and I'd give it the full five stars, but for the barely discernible marks currently remaining. Another thirty minutes work and I may have a five-star outcome.

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.

Great item. Cleaned my windows and was easy to use. The material is good quality

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.

After I tried a tiny bit with my cordless drill, I just bit the bullet and got corded drill like the instructions said to do. The corded drill allows for applying a LOT more pressure and so I had started to really get my hopes up, but the difference is seriously underwhelming. I thought I had a perfect candidate for this product since the scratches on my windshield are many, but they are extremely shallow and superficial. They came from my using a green scrubby side of a kitchen sponge to try to clean some water spots off. Green plastic scrubby sponge backs will totally scuff up a windshield. That green scrubby plastic must have some abrasive fragments in it or something. I polished for 20 minutes or so at a stretch (enough time for the metal frame, 1950's era drill I found at Goodwill to become uncomfortably hot) with plenty of polish for a total of about 4 hours. I don't think any of the scratches are gone or even significantly reduced, but it did polish the glass making for less glare at night which was the biggest problem I was having with the micro-scratches on the windshield in the first place. Now I can see in the rain at night, and ignore the scuff marks. It may not stand up to the promises of the manufacturers or the hopes of customers like me, but I'm not sorry I bought it.

This product worked very well, but it is not a "quick" process. You cannot expect scratches to just disappear after a few minutes of polishing. I had a total of 6 scratches in my windshield due to a wiper blade issue. (I bought the vehicle used with the scratches so I do not know exactly what caused them.) Two scratches were 20" long, two were 12" long, and the other two were 5-6" long. The long scratches were the deepest. If the polish splatters on the paint (very likely), it does come off fairly easily with water. However, I covered my hood and roof with old sheets, draping them over the side windows, mirrors and the fenders. I used 1/4" green painter's tape to mark the scratches on the inside of the windshield to make them easier to see on the outside as you progress through the polishing. Follow the instructions! Have a spray bottle of water and use it frequently. After 30 seconds or so of polishing, the glass will be warm - the heat generated is part of the process, but you do not want the glass to get too hot. Wet the glass with the spray bottle, and as soon as it cools a bit, go back to polishing. With the applicator pad damp from the water, you do not need to keep adding polish as the pad will become saturated (same principle as polishing/waxing a vehicle). I spent approx. 2 hours polishing the 6 scratches, and approx. half a bottle of product until I was satisfied with the results. Did the deep scratches totally disappear? No. I can find them, but I have to look real hard, and can only find them at a certain angle. If I asked someone, "Are there any scratches in this windshield?" They would likely say, "No". If I pointed them out, they may see them, but they may not. I would describe the result as a "polished, slight groove". Tips: ** Using water also helps with lubricating the pad to rotate smoothly (less friction). ** Hold the drill / polishing pad on a slight angle to the glass surface. It is very difficult to hold the polishing pad perpendicular / flat against the glass and have control of the areas to polish. ** If you have multiple scratches to polish out, spend a few minutes on one, move to next one and polish, etc., and keep repeating the polishing cycle. This will allow the glass to cool in a specific area, decreasing the amount of overall time spent.

The Glass Polish 21005 DIY kit is a solid option when you want to reduce scratches or hazing on windscreens and other vehicle glass without paying for professional work. It’s easy enough to use, the pads hold up well, and the compound does make the surface clearer and smoother. Just don’t expect a factory‑new finish, deeper scratches remain visible, and the final result depends heavily on patience and technique. Still, for light marks and general clarity improvement, it delivers a “better than before” outcome that feels worth the effort.

Voldoet niet echt maar mss moet ik een machine op 220v gebruiken, deed het met een accuboormachine van Bosch, maar krasjes blijven zichtbaar

Utilisé pour effacer une rayure sur une vitre d'une baie vitrée ainsi que quelques micro-rayures sur d'autres vitres. Résultat impeccable ! Quelques conseils pour un bon résultat : utiliser une perceuse filaire de bonne qualité (pas une batterie qui perd en puissance) et être patient car il faut repasser plusieurs fois sur la zone, et surtout regarder le tuto vidéo du fournisseur avant de commencer — il est très bien fait. Kit complet avec tout le nécessaire. Je recommande

Nice

It’s working fine
