DIY 75mm Windscreen Polishing Kit for Car Glass Restoration, Remove Wiper Blade Damage, Fine Scratches, Haziness, and Water Spots, Restore Glass Clarity and Shine - GP21005

Nice

It didn't remove any single wipers scrach from my windshield. Followed the instructions by the letter, nothing working. 45 minutes from continously polishing and wetting and checking glass temps. You can't even feel my windshield wiper scratches with your fingernail, and yet, it didn't remove it. I don't recommend buying this item. people saying it worked, which I believe they had strong stain on their windshield thinking it's a scratch.

I bought the kit to remove windshield wiper scratches. The scratches left a section of haze and scratch lines. The haziness was from very light scratches. I used the kit with a DeWalt 20v drill (I wouldn't recommend using anything less than a 20v drill). It can be tiring on the wrists using a regular drill and takes 20-60 mins of polishing depending on how much you want to polish out. It worked great to get rid of the majority of the light scratches and haze, to the point that I can see clearly enough out of that section again. You can still see scratches, so if your trying to remove any deep scratches, this won't work and you'd need a multi step sanding and polishing kit (personally I wouldn't recommend diy-ing a multi step unless you're willing to replace the windshield if it doesn't turn out well). In hindsight: - Don't let the compound dry on the windshield. Do small sections at a time, keep it wet with a spray bottle of water, and wipe and rinse the compound off as soon as your done. If you windshield has pits in it, the compound can fill them and if it dries it's a bit of a pain to clean them out (I had to use a soft nylon brush drill attachment and soapy water to clean them out). - I decided to lightly polish the rest of the windshield, but that ended up making all the pits in the windshield much more noticeable because all the minor haze on the rest of the windshield was polished off. I got used to it after a couple days but in hindsight I would've just stuck to only polishing the scratched area since polishing the rest didn't really make an old windshield look better with the pits. Overall, if you have very light scratches/haze bad enough to affect visibility, I would recommend this kit, and only to use on the affected area. If you have deep scratches you can feel with your fingernail, this kit definitely won't remove them. In that case I'd actually consider replacing the windshield if it bothers you enough.

About a month ago I noticed a 6" scratch across the top of my 2014 Grand Cherokee backglass. Needless to say it was real bummer. I think that the dealer did it during the complimentary wash after service, but I discovered it too late to go back to them. It was deep enough to catch a fingernail and really showed up against the privacy glass and headlights from behind. I tried to buff it out with a cotton wheel and some compound and managed to create a bunch of light to medium parallel scratches and some haze. Now it really bothered me (scratch + stupidity) and I actually got a price to replace the glass. I saw this product and after reading the reviews, I decided to give it a try. My main concern was not to cause more damage so I emailed the company with my questions. The guys there are great and super responsive. While they honestly didn't know how much of the deep scratch could be fixed, they assured me that it would not make things worse and probably would take out the secondary scratches and haze. They also helped with my tool choices and general approach. That gave me the confidence to proceed. I have a lot of automotive experience and having some skill working with your hands is a plus. Working carefully and following directions is critical. I tried my cordless drill, but it seemed to run slow as the batteries ran down, so I ended up using a corded drill rated at about 2000RPM. It is not a quick or clean process. I draped and masked off the area to avoid splattering the car and garage. After 2 hours I managed to get results that were more than satisfactory. The main scratch has been about 80% reduced. You can see it occasionally in certain light conditions, but it no longer refracts at night from behind. As far as I'm concerned that's a fix. More importantly I eliminated the secondary scratches and haze that that I had subsequently caused. I may even have been able to get more of the main scratch out, but I think as you change the profile of the glass surface significantly, it may start to "lens" and cause some distortion. In my estimation it was not worth going deeper.I think this result is the right balance for me and I'm very happy with the results.

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
