Glass Polish 3.4oz (100ml) Glass Polishing Compound for Professional Optical Polishing of All Glass Surfaces - 1.2 microns - GP14004

I recently got a new glass cooktop. Being used to gas, I was excited that glass cooktops are easy to clean, as I feel that's the only advantage over gas cooking. I was dismayed when I accidentally scratched the top with the bottom of an older pan, and I didn't know what to do. I did a little Googling and found this glass polish (originally used for automotive purposes). I did not attach the cleaning pad to a drill because I was afraid I wouldn't apply the right pressure and might crack the cooktop, so I just used elbow grease and followed the instructions on the bottle. I only used a teeeeeeny amount, scrubbed with the included cleaning pad in a circular motion for a few minutes, and MIRACLE!!! The scratch (which I felt was pretty deep and terribly unsightly) was GONE!!!! My cooktop looked brand new, and I'm pretty sure I have enough of this stuff leftover for 100+ more cleanings. I was so excited that it worked so quickly and easily, I sent before/after pics to my mom and my friends (well, maybe I'm also a dork). They were equally impressed and ordered some themselves to fix their own glass cooktop scratches. IT WORKS! I could not be happier with this purchase!

I had a ~quarter size cloudy (either scratched or etched) spot on my windshield that I had caused by trying to clean water spots using an abrasive, acidic cleanser (oops). I though my windshield was ruined.I had never attempted to polish glass before, but I figured I give this glass polish a try. This polish successfully removed the cloudy spot. I did not have a buffer, so I used a cotton handkerchief and scrubbed/buffed by hand. At first I was not successful, then, in desperation, I tried scrubbing with more pressure, pretty much as hard as I could comfortably press with my fingers. That worked after less than a minute of scrubbing. The glass looks like new. I can't even find the cloudy spot if I try. Awesome product! Exactly what I needed.

Our vinyl double pane glass slider to the patio has hundreds of small scratches from the dogs over the last 15+ years. I purchased this (along with the other particle size) and the wool pads. Tried a small spot with both grades and a DA polisher with 5 inch pad as well as a circular drill with the small wool felt pad. After a 20+ minutes. no real improvement. My guess is that it would take 40 hours to polish the thing.. not worth it. Seller was prompt and packaged well - but product can't perform miracles.

Light polishing compound. Used to remove thin light scratches in the glass cover of a mantel clock. I picked a light compound knowing it would take extra time and effort to remove the scratches but it was worth it. Expect to spend time and effort.

Works well for minor glass scratches.

So, I've never polished glass before, so take my review with a grain of salt.I was trying to buff out a scratch from my glass cell phone screen. This product is abrasive, and left a significantly changed texture where I used it. I suspect it is "scratching" the glass. While it didn't make it cloudy, if I had kept going, I bet it would have ruined the screen.So yeah, bad experience, not good.

I purchased this product to remove some fine scratches in a glass plate. After following directions and trying four separate times, I was not able to remove any of the scratches.I tried doing it by hand: I tried using a Dremmel polishing wheel, and I tried a buffing wheel.This compound did not work for me.

Works as advertisedWindshield of my new Acura had several scratches that looked like someone sanded with 400 grit. (See before photo). Some were deep enough to feel with a finger nail (not all of the deep ones came out). Dealership would not fix the problem and claimed it couldn't be their fault.I bought this product and Griot's Garage glass pads on my Porter Cable 7424.1. Cleaned the window carefully2. Taped off the timber mouldings and covered the paint with plastic garbage bags3. Added about 1 teaspoon in middle of the pad and sprayed water to dampen the pad4. Started at setting (1) on the Porter Cable which is about 2400rpms. Had noticeable improvement but I had so many scratches that I repeated this 4 times before going to the next stage.5. Then I turned it up to setting (3) on the Polisher and went over it 10 more times with decent pressure. Every 4 passes I wiped the glass clean with water and a paper towel. Then added another teaspoon to the pad. Always add water to stop it from drying from friction.6. Once I got the major areas looking good, I made 3 complete passes across the windshield. This took off the old RainX and that annoying frame that the wiper blades make in the glass.7. Took off the tape and plastic. Washed the whole car.8. Resealed the windshield with AquaPel.9. Didn't remove everything because I would have to grind down the glass pretty deep. So I am happy with the turn out and it looks great. (See after photo).
