TechDiamondTools Diamond Polishing Compound Polishing Paste 4,000 Grit 2-4 Microns for Marble Glass Metal Rock Jewelry Resin Silver Chrome Gemstone with High Concentration of Diamond Powder USA Made

I had a small area of my windshield that got light scratches from foolish use of a super fine grade sandpaper on a nicked area. I tried a few different ways to fix the scratched area but nothing worked. I was beginning to think I would permanently have a small, unsightly area where the glass was dulled; this was especially visible when the light hit at certain angles. But I came across TechDiamond polishing compounds while searching for glass polish. I took a best guess and ordered the 4000 grit/2-4 micron product. I heated the tube for 10 seconds in microwave, put a small amount on a microfiber cloth, and polished rapidly in circles over the affected area. 5 minutes later, the glass was shiny and smooth again. I could not believe how rapidly and effectively this solved the problem. While driving, I could barely see where the scratches were. I would say it was a 95% fix. I could probably do a little more on it but I don't want to risk going too far, since it's really unnoticeable now. (Note that the scratches I'm referring to were very light and shallow - they were not so deep that you could get your nail into them). Very pleased with this product. I think I could make use of it to polish other things like lightly scratched watch crystal.

Before and after. The mason was removing a brick ledge and his grinder nicked the window leaving a half dozen scratches. Not too deep but you could feel them. He felt terrible and offered to replace the pane ($600 was the estimate...). I had heard about glass scratch removers and ordered this and a ceramic oxide. The ceramic oxide was tried first and helped some but then used the this diamond compnound (4000 grit) and it got rid of 95% of the scratches. That was by hand so I am sure an orbital disk and maybe a more agressive grit would take out the last 5%. 1/50th the cost of new pane.

I had a 3.5 mm scratch in my magnifying glass-lamp (Neatfi Bifocals 1,200 Lumens Super LED Magnifying Lamp). I have not used such polishing products before. The scratch appeared mostly superficial. I bought a "mirror" polisher since it was mostly superficial. It took 20-30 minutes of polishing and the scratch was down to 1 mm size. This thickest area took an additional hour or more to polish out. The clarity of the glass now appears perfect--no scratches from the polisher, perfect translucency, scratch removed. I used an eyeglass cleaning cloth to polish with. In retrospect, It may have been better to buy a thicker polisher to remove the scratch and finished with the mirror polisher for time.

I purchased this to add onto the one side of my strop for fine honing. With a thin layer and rubbing it into the leather and letting it dry/cure for 24hrs. I have been able to put a mirror shine edge on my knives. The attached photos are from my Spyderco Para3 that I have had for many years and with the use of this compound has been a very big help.

This product was something I needed once I started my sharpening journey. The first aluminum oxide compound I purchased was a great beginner compound. After a while I knew I needed diamond compound in order to get into a whole other league of sharpening and polishing. After looking at many products I decided to try this brand out and wow did it perform! Left my knife hair popping sharp with a mirror polish! If you are hesitant trust me when I say this is going to be a staple in your sharpening routine! Great product!
