3" Felt Polishing Wheel with Gordon Glass Cerium Oxide Polishing Powder - 8 Oz

First of all, I have some idea of what I'm doing, although I have never specifically buffed scraches out of glass. With ample study, I chose this product. It turned out to be the perfect choice! I had scraches in my brand new windshield from nylon packaging tabs mistakenly left on new wiper blades for one rain storm. I could just barely feel the scraches with my finger nail. I own a cheep random orbit car buffer, so used that rather than the buffing wheel that came with the kit. It works faster and with the edge, I could focus the buffing to just the narrow, arch shaped scraches. So I could see where the scraches were while buffing with the slurry, I marked them on the inside of the windshield with a wax pencil. Except for climbing up on the hood and bending over with the buffer, the process all went very well. There was about 1 hour of actual buffing to the job and another hour of setup and clean up. The nylon tabs were about 1/4" wide, leaving a bunch of fine scraches adding up to visually, a scrach 1/4" wide but not too deep. The buffing compound actually buffed the "sides" of the individual scraches, removing all the "frost", but leaving the 1/4" wide area with a very fine wavyness. To buff that out would have required the initial use of a courser diamond compound to remove a lot more glass material...and a lot more time. For the 2 hours invested, I am very happy with the results. For removing scuffs & fine scraches, this Cerium Oxide is the perfect stuff. However, to curb expectations, experience buffing, for instance on paint, is a huge benefit. Buffing scraches out of glass is not easy. Results will differ with users.

I had some scratches on my windshield from my mistake of using a razor blade on the glass. It left a bunch of small scratches on the 2inx2in area. I tried buffing it out with auto polish compound it didn’t remove anything. I then tried toothpaste after reading that may work, it did not. Finally I came across this glass polish set. I tape off my car aside from a small square where the scratches were. After about 20 mins of polishing the scratches were all gone. It’s messy but works wonders! Beats paying $1000 for a new windshield. The scratches are completely gone. Very happy with the results.

Works well enough but doesn't come with instructions. I tried another similar product that comes already mixed but with less already mixed oxide and with instructions, although this product gives more than enough oxide to provide multiple applications and has a better polishing pad. If you can even call it a pad as it is quite thick and sturdy.

I bought this after making a bone-headed mistake in our kitchen. I was washing the widow above the sink and was feeling some grit on the glass. Rather than walking out to the garage and fetching a razor blade to scrape this grit off, I simply grabbed the Scotch-Brite and scrubbed it off. To my horror, the glass had fine scratches over an approximate 14" x 12" area. Using the cerium oxide is pretty simple: make a slurry, soak the felt wheel, attach wheel to drill, dip into slurry and start polishing. I kept a squirt bottle handy and would sometime pre-wet the area I was working on. My biggest challenge was the fact that the glass is in a vertical plane and the window was just a few inches further away than I would have liked. This meant that I would work on an area with my arms almost fully extended. I would polish until my arms gave out after a minute or so. I would then wipe down the area with a rag and paper towel to dry and see what progress I had made. Then repeat, over and over. I put in 2 hours of this activity on the first day and then 2 more the second. At that point, only I could see the scratches if I maneuvered my head just right with the sun back-lighting. With my wife's permission, I was allowed to call it good. I think 2 more hours would have done the trick of bringing it all the way back but with louvered blinds hanging in front, only I will ever see them or know they are there. Had I had some way to get the window out and laid on a flat surface, this job would have been immensely easier.

Well, I used the product exactly as directed. The good news is that the scratches are gone. The bad news is that the product deformed the glass and now I have what looks like a large blurry area, kind of like a heat shimmer look, where the scratches were. This is worse than the scratches originally and now I have to replace the glass. BEWARE!
