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

Works great, Accurate descriptions, Fast shipping, Great price, Great seller A+++++

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.

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 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.

UPDATE: I ended up buying a new tank because this stuff was so annoying to work with. I purchased a used aquarium and didn't notice how scratched it was before I took it home. Instead of buying a whole new tank, I wanted to try to buff out some of the surfaces scratches, knowing that the deeper ones (ones that get caught by your fingernail when you run across it) are NOT coming out. I was glad that the kit came with the powder AND the buffing head plus it is Amazon's Choice so it felt like a no-brainer. The box that came in the mail with the products had NO instructions. I had to come back to the listing to see that there is still no real measurements for how to mix the cerium oxide. It says something like, "use a couple tablespoons and add enough water to make a slurry (thin, paste-like)". In reality, other sources say to NOT make a paste and that the mixture must be 2 parts water to 1 part cerium oxide powder so it is relatively watery. I had used the buffer head with the cerium oxide "paste" like the product listing told me to for over an hour and NOTHING changed. I kept the surface wet and cool so that the friction of the buffing did not heat up the glass and I applied equal pressure to make sure it was level and everything. I'm going to try again with 2 parts water, 1 part cerium oxide and with a handheld buffer instead of attaching the head to a cordless drill. It is VERY time consuming so it will kill all the cordless drill batteries for sure. I admit that it's better to try this before purchasing an entirely new tank or piece of glass/mirror, but you will be putting a lot of time into it and it is frustrating when the company does not even tell you how to properly use the product they sold you so you end up wasting time and a ton of product. Granted, I should have done my research beforehand, but it is still annoying.
