GLASS POLISH PRO 1.76oz (50g) Cerium Oxide, Fine-Grade Glass Polishing Powder, Refined Formula, TREO 95%, 2.5 Microns, White – GP90001

I cleaned my frost covered windshield with the wrong "scraper" leaving 6-8 rather long scratches and a few short ones. I didn't want to replace the windshield and found cerium oxide mentioned on the internet. My fingernail would hesitate when I slide it across the scratch but did keep going. I thought that the scratches may be too deep for this product. I only ordered this small amount since I didn't believe that it would work in my case.I was wrong, it worked well.I used a small dremel type tool and a felt pad that was only about an inch across. I marked the scratches on the inside of my windshield with a black magic marker, giving me a target area to work on.I mixed up the powder with enough water to make a paste, dipped my felt pad into it, and starting working on the scratches. I followed the scratch lengthways and worked back and forth not knowing which would be best. I kept the pad flat against the glass and only used a moderate pressure. If I pressed too hard my tools would slow down and I would know to ease up a bit.The small scratches came out rather quickly. The deeper wider ones took a bit longer. I would clean off the residue and wipe the inside of my windshield with alcohol to remove the black marker. If I could still see the scratch I repeated the application process.It took 3-4 trys to get all of the scratches out.The black marker helped but a white one might have been better. The black was a bit hard to see.Try this on your scratches. It won't hurt to try. It wasn't that hard. Just allow a bit of time to do a careful job.You might want to wear eye protection and an old shirt. The rotary tool flung the paste around a bit.Good luck.

Works well. Got scratched out of windshield

Muy bueno.

Was ok. Didn't buff quite as well as I had hoped for.

Do not buy does not work I use it on my windshield and it did nothing it is a waste of money I bought pads and everything it does nothing when you got scratches in your windshield it does not work don't let him lie to you

This works very well for my Pebble Time, but one warning, it does appear to take off some sort of coating (oleophobic?) on the glass of the watch. So be careful if this is something that you want to retain. Mine had some fairly decent scratches on it that made it hard to see through to see the time, so for me it was worth losing this coating.Because of this coating, this took quite a bit more time to polish as a small circle appeared when I was polishing the scratches off of the watch. This circle looked really clear and smooth, but there was a border where this coating was coming off, so it looked strange. Since there was this border, I ended up having to polish the entire surface in order to make the watch look normal. I've included screenshots of how the watch looked initially, then how it looked after a bit of polishing, and then how it looked in the end.It took a lot of time to polish out the scratches, but it did the job. All in all, it took like 1 and a half to two hours to polish by hand only. Probably would have been a lot quicker if I used a dremel. I hardly ended up using much of the powder, but at least I know I have a lot to spare if I need to polish any more glass. In the end, that watch looks much better; almost like new.Update: After using it for a while, it definitely seems a lot shinier than it used to be as there is a glare that is a lot more prominent on the screen making the watch a bit harder to see, but in my case, it was definitely an improvement over how it used to look.

almost fifteen dollars is way too much to pay for ten ounces of this product. It has the consistancy of baby powder, reason why I ordered it was to remove scratches from my windshield due to animal damage. It did not work unfortunatly but instead left overspray everywhere. Now this probably is not how the product is supposed to be used but still, it should be cheaper.

Excellent results. I really wish I would have taken a before and after photo. But in my excitement to try it I forgot. If I post an after photo now you wouldn't believe me. Anyway, I used this on a Pixel watch I scratched with sand while at the beach. The scratches were pretty significant so I figured I had nothing to loose. WOW, the results are amazing. I will say, it was about half an hour worth of work with a Dremel and the best results came after I figured out I should be buffing straight down. Not with the side of the wheel. Do it just like the video shows. But be aware that with some of those felt wheels the metal tip goes all the way through. Don't use those, make sure to have plenty of felt on top of the bit that holds the wheel.
