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

THIS WORKS!!! I can't believe how well it removed light scratches from my car windows. It must be used with a cerium oxide polishing tip and power drill to buff out scratches correctly, but it works like magic. Together, everything cost around $50 and took maybe 15-30 minutes to complete. Called around tons of places to see if they buffed out scratches on windows, and no collision or window place would do it, instead, they wanted to charge around $1700 for all new windows. I can't even describe how happy I am with this product. Threw in some before and after pictures.

Worked well on scratches

The media could not be loaded. It works. However, you really need to do multiple applications and have some type of buffer. Keep a spray bottle on hand and have some patience. It does work great on water spots but does not remove scratches.

Shower stall clear glass with 10 years of water spots. Used felt pads, 5", hook and loop style. The cerium oxide is a ultra fine abrasive, with particle sizes finer than other polishes. This product does not state how fine, but the white cerium is typically much finer than the pink/red stuff.It cuts by using particles embedded in the felt pad, so after applying it to the felt, smear it around to be sure it penetrates the felt uniformly before starting the polisher.Even though it is worked wet, the liquefied stuff on the surface is not doing the cutting, only acting as lube. Faster results are to be had when it is well thinned on the work, but don't let it go dry.I started off trying my Dewalt random orbital, but that was slow and the variable speed was faster than ideal.I switched to a corded rotary polisher that could maintain a steady 2500 to 3000 rpm even when pushed firmly. Pressure is required to keep the particles in the felt in contact with the glass. The rotary was far superior to the RO for this work.This was eventually effective, but too time consuming as an only step, so I tried diamond polishing pads, wet. The 3000 grit worked somewhat faster and left only light swirls, and the 1500 was very fast with medium swirls. Both are worked wet with frequent spritzing with distilled water, same rpm range as the Cerium oxide but less pressure. I could see the grayish water spot residue coming off the polisher disc as I sprayed water on the surface.1500 diamond wet, 3000 diamond wet to address the bigger swirl marks, then Finnish with the 3D cerium oxide. Glass now looks like it just came out of the factory. Plan on multiple hours, and get a good light source to see what you are doing.

Save your money. This product is less effective than a traditional cutting compound such as Meguiars M110.I tried removing light scratches with this product, and it did absolutely nothing. M110 removed more in 30 seconds than this product did in 10 mins.Total fail.

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!

It cleaned up the glass quite well with the carpro rayon pads. It removed most of the swirl marks in my wind shield along with some wiper marks. Just have to keep it kind of wet with a spray bottle to increase the work time. It also helps to add a little baby shampoo to the bottle maybe a drop or 2.

Pretty much useless when it comes to even small scratches.
