TechDiamondTools Kit of 3 Diamond Polishing Compound Polishing Paste USA Made 5000 14000 50000 Grit for Marble Glass Metal Rock Jewelry Resin Silver Gemstone with 25% Diamond Powder

Great diamond paste!

Had bad scratch on the AR coating of a sapphire crystal, used all 3 pastes in succession, scratches completely removed and the sapphire looks better than new.

I was able to achieve a nice polish using on stones using these. I wish the syringes held more, but this seems to be the standard size

Used for one v8 engine. Also one small engine. Grit is good 👍 work's well. Suction cups were fair at best. But get the job done. Probably need new Suction cups next time around.

I used this to polish a tungsten carbide sizing ring. Nothing I’d tried before could remove the galled metal buildup that was scratching the work pieces. Two or three passes with the medium grit on a felt pellet removed it all, leaving a fine haze, which the fine grit removed, leaving a mirror finish. No change in internal diameter was noted.

I use these polishing compounds to polish steel gauge pins that are used as mandrels to size brass cartridge cases. I thought I had the pins polished to a very smooth finish but after using these compounds it's not even close. The pins are like chrome. Extremely smooth. And you just use a very small amount to get a great finish. Goes a long way. Highly recommended and I would buy again.

This product seems to gum up and peel off quite a bit. I'm sure you could use it to polish your products, but don't expect to get a lot of use out of it. After a little while the product will ball up and be unusable. At least that was my experience using this item.

Not sure of all of the uses, but this stuff removes scratches from watches like nothing else. You just need a little patience and a strong rubbing finger. With some cut up pieces of CLEAN microfiber cloth, following the step by step guide shown in the photos does the trick. Use the grit you need based on your current problem, and only use one small piece of cloth with each grit. You only need a small piece of cloth because you don't want to waste the product. It doesn't require too much. The rag will just soak it up otherwise. I started with 1500 grit for a decent scratch I got on my watch recently and I worked my way up to mirror polish. Just be prepared to rub for awhile in the beginning with your starter grit. Before you know it, the scratch is GONE. It's amazing stuff and I'm happy to finally have my only mechanical watch back in rotation. I feel a lot better knowing I can remove scratches from the glass. Highly recommended product. Now I just need something like this for the stainless..
