3D3D Glass Polish – Cerium Oxide Glass Scratch Remover for Car Windows – Restores Clarity & Removes Wiper Marks, Swirls, Water Spots - 16oz

It takes a little while but this stuff works for shallow-ish swirls and scratches. I had a classic car with windshield scratches from either old and deteriorated wiper blades or some grit captured in the rubber. It also had a bunch of swirls. These were noticeable if you caught them in the right light. About an hour with this compound, my Dewalt DCM849 rotary polisher, and a glass polishing pad had my windshield almost as good as new - at least as far at the scratches go. It won’t get things like rock chips or deep scratches out of your windshield, but for scratches equivalent to maybe 600-800 grit and up, this will work.

I am so happy that this product worked. It took patience but after running my 6" DA on full speed with a felt pad it took ALL of my wiper scratches out. Save me from buying a $500 windshield. Just be patient and keep working. Took maybe an hour and a half of hard work, repeat, repeat, repeat but it finally worked.I used a bright shop light to see the scratches. Put blue tape on the outside and followed up with tape on the inside so I could see where to work.

Be patient and use a spray bottle. I used this on a windshield and it took out all but the deepest scratches after a couple of hours of work. Rinse your pad often and check the temp of the glass frequently. Start and stop your buffer while touching the glass. Be careful and mask off the area as this stuff can fling. I was very satisfied with the job I was able to do. 95 percent of scratches gone and no distortion of vision.

I had minor scratches on the driver side window. I used my orbital polisher and followed the directions. it did nothing. I spent over a half hour with the polisher. a waste of time.

Had some scratches on my windshield of my new truck. Bought this to remove them, it did not work as I was hoping. After working on them for about an hour they were still there. After doing some research found it will take a while. I have not tried it again yet but will. But the scratches are better. I feel that it's a good product. Found out that it is messy so cover things up before using. And have patience.

Here was my original assessment. Follow-ups below:I’d first like to tell 3M who makes scotch bribe a few things but my review would never be published. You see it was them who got me to where I needed this glass polish. If you google “can you use scotch brite on glass” you will be returned the results telling you how great it is on glass. So I proceeded to use it on the rear glass of my brand new C8 Corvette to get hard water spots off. When I wiped the glass cleaner off I was presented with all my new scratches on the rear glass of my $100k sports car. I’m anything but happy about it as you can imagine.So in comes this product. Above you see some before and after pics. That’s a full hour of attempting to polish by hand. I used a rotary polisher on the other side (not photographed). Best I can tell is all I got out of this was a sore, but well worked out, arm. The rotary just slung stuff everywhere so no better results with it. The polish gets sticky within seconds. I hit it with water spray and that certainly loosened it but but I saw zero improvement to the glass. So far this has been a waste of my time and money. At this moment they get two stars because it appears slightly better between the two pics attached but as you can see, some of those micro scratches are un-phased and that was a whole bunch of my time and effort.Tomorrow I have some glass specific pads coming. I’ll give them a shot and update my review afterwards.Update 1: As promised here’s another. It amazes me that damage to glass took 30 seconds to cause and Ikm now 2-3 hours in and still not back to being restored. Today the 5” drill driven applicators showed up and I learned a few things. 1.) These are WAY easier to work with and less messy vs my rotary. 2.) One thing you can’t judge from watching videos of guys showing how to do this is how hard are they pressing. They always say to let the compound do the work but after 45 mins of pretty much getting nowhere, I put so pressure on it. Like more than you think you should need. Surprisingly, THAT finally started to give me results. I worked it with some pressure and the drill based pads and this removed some of the scratches in a noticeable way. Spent an hour in this fashion and retired for the day. One thing I’m still not clear on his exactly how much paste I should be using and when do I give it some more and when do I give it some water spray. This is still trial by error. I feel like I’d like to have some 3 inch pads to use for more focused attention on the problem areas. More to come. Man do I regret using that scotch brite.Last update: I now have over three hours in this. Still favorite tool was the drill with the 5” pads. Worked better than my rotary. I will keep my review at 3 stars. I also tried some of the powder cerium oxide and it did no better than this stuff which means this stuff works as well as the powder. In both cases, neither one removed my micro scratches caused by the 3M scotch brite but both drastically reduced them and their effect. Most people would not notice them but I know where every single one is. None of these scratches can be even remotely felt with a fingernail. I tried multiple methods, varying pressures etc and after 3M plus hours of elbow grease, only the micro of the most micro seem to be pretty much gone. Again….it did drastically improve the situation but I think the only way to have a new looking piece of glass…is to replace the glass. Thx a lot 3M Scotch Brite!

I used this to get a nasty scratch out of an old CRT tv screen that had fallen off it's stand. Well worth the price as it saved the hard to replace TV and only required about 15 minutes of buffing by hand

After a car detailer scratched my mom’s windshield trying to remove hard water spots, I found this glass polish. The one piece of advice I’d give is to follow the manufacturer’s advice from their YouTube channel for this product. “Continuously add water as you polish!”
