Cerium Oxide High Grade Glass Polishing Compound - 1 lb (Pack of 1)

first, the photo doesnt show much but with it wiped off you can see the other side where its not been done yet .. anyway the shield had light scuffing from years of sand and bad wipers etc .. that said, the product will take out scratches and scuffs that arnt deep and will likely take at least 2 applications ..it works but cuts slowly .. no bad qualities like hazing or uneveness, it just takes 'x' amount of time being worked in to take the scratches down ..i spent about an hour total actually on the machine polishing, both sides, and it could use another going over a time or two to get the last scratches out, but theyre definitely better, lots better ....ok, i did 'some' experimenting while i was doing it and i'll tell you what i know so far - #1 - you 'definitely' will want a power tool to do something as large as a windshield and you 'definitely' DONT want a spinning tool like a polisher, youll want a DA 'for sure .. the stuff will be watery no matter how you mix it and a spinning tool like a polisher will fling orange stuff literally all over everything in your garage to the back wall😂 but a da works great just keep it on the work so it doesnt spin up .... 2- mixing - i used a dish soap bottle and spooned in maybe 1/2" in the bottom then 'slowly' add alittle water and swoosh it to mix, it wont thicken up, if theres not enough water it will clump, if it does add just a bit more ... now, #3 - apply it to a 'foam' pad you can affix to your da, NOT the windshield itl just roll off, itl be watery .. pour it onto the middle of the pad and spread it around, keep adding until it covers to almost the edge but not on the edge, it shouldnt even be close to dripping .. now your ready to hit it to the shield, that much did half the shield and i just kept going over it until it seemed like it was drying ..it doesnt seem to be as effective once it hits that dry point ..so a cool temp works better .. seemed to stay wet about 15 minutes for me .....at that point get a wet towel and a bucket of water to rinse it in and wipe off everything, let it completely dry, buff a tad with a T and assess where your at .... just repeat the above to hit it, or the bad spots, again ...the stuff is pretty clean actually and isnt greasy and doesnt stain stuff, it wipes right off of anything ,so thats good ... but again, you just dont want it flung all over the place, so careful with that ..... so im happy and quite impressed with the results, id say theres enough in that container to do 10 windshields if things are done efficiently😆 .. finally, it works slow, so no way will you be cutting out deep scratches your nail will hang on, but light scuffing from dirty wipers, yeah that can be buffed out with this stuff.

First off, I'll start by saying I'm definitely not a professional detailer. I have a bunch of detailing products, but simply because I enjoy having clean vehicles. One thing that has always bothered me is scratches from windshield wiper blades. I bought this to use on the windshield of my Saab 9-3 that had a significant amount of scratches. I don't know if it was necessarily the blades, but the car originally came from Miami Beach, so it may have been some sand as well. It was simply dangerous to drive the car at night because oncoming headlights would glare so bad it would be hard to see the lines on the road.I have a Griots Garage DA polisher and bought the glass polishing pads they offer plus their glass polish (remove water marks, but did nothing for the scratches) Anyway, after reading about this stuff on some detailing websites, I decided to give it a shot. I bought a 1lb container of it, which was entirely too much. After doing my windshield I have probably 95% of it left. I had a clear water bottle that I decided to sacrifice to mix this stuff in and then store for future use. Worked perfectly. I mixed 1:4 ratio with water. 1/4 cup of cerium oxide and 1 cup of water for ease of measuring.Once it was all mixed and ready to go I squirted it on the windshield and started polishing. I set the polisher on a speed of 5. I worked in ~2 square foot areas at a time, letting it start to haze and turn into dust before squirting more on the windshield. This seemed to do the trick. It's a slow and tiring process - it took around 2 hours until I was satisfied. After it was dark I took it for a drive and sure enough, it worked. Almost all the wiper-blade scratches were gone and there was significantly less glare from the lights. There were a couple spots that need a second go at it with the polisher - especially right in the middle of the windshield where the passenger-side wiper stops as it goes up the windshield and overlaps the drivers-side. I did a second pass over the entire windshield the next day, and I'd say 99.5% of the scratches are now gone. There is a faint line where the passenger-side wiper comes to a stop nearly vertical on the windshield but considering this stuff is 25 times cheaper than replacing the windshield, I'll settle for that.Things to note:-It makes a huge mess. You'll need to wash your car after you do this. Don't park any other cars within 5 feet of where you're working or you'll be washing those cars too.-It settles quickly; be sure to shake it up every time you spray it on the windshield-Seems to store well long-term when it's mixed with water-Take your time and make sure you get everything, especially where the wipers stop.-This will remove every bit of Rain-X you have on your windshield and make rain basically stick to it. You'll certainly need to re-apply Rain-X.-It doesn't really remove rock pitting. Maybe some very minor pitting, but it's not going to sand out millimeter deep tiny rock chips. You'll need a new windshield if you want those to be removed.

I restored front and side windows of a truck that was severely scratched.I have learned so much through trial and error. You will need a lot of this if you have deep or several scratches and you will need many many hours of man power on a drill and or buffer. If I could have had a friend just to spray water as I buffed that would have saved some time. NEVER BUFF DRY. And be generous with this stuff. Sand deep scratches with sand paper from course to very fine before using this and be very patient. If your wheel isn't balanced you can use a larger wheel with a smaller pad if you are careful or an unbalanced wheel if your really careful and good. I saw a review about someone crying about the wheel they got on another product. Plan to get several from different sources they are relatively cheap and it's good to have more than one buffing source like use 2 drills one corded and one not, and a larger buffer. Anyway this product is great.

My wife’s windshield had some large scratches from a windshield wiper. The rubber blade wore through and the metal portion of the wiper left some serious marks on the windshield. I tried some pre-mixed Cerium Oxide glass polishing compound but that did not do much to improve the scratches. Then i got this powder with some felt pads and went to town. It took multiple applications over two days, maybe 3 hours each day. But the scratches are no longer visible.

Seems to be good product, but I expected it to come in a resealable container as the picture shows, but it just came in a plastic bag.

This is by far the best value for the money compared to all the other Cerium Oxides offered!
