TechDiamondTools Kit of 3 Diamond Polishing Compound Polishing Paste USA Made 14000 100000 200000 Grit for Marble Glass Metal Rock Jewelry Resin Silver Gemstone with High Concentration Diamond Powder

I use these for polishing glass watch crystals. The polishing compounds work perfectly. I do it by hand with this company's wool cloths, so it is NOT quick. If you have a scratched watch crystal that you can't find a replacement for, give these a try!

I use a small amount on a leather lap and it does a great job. Grits are consistent and there seems to be plenty of abrasive per volume - a little bit goes a long way.

This is a good product for the price, but if you are going to use it on a leather strap for knives, you need to apply evenly with a credit card or something, then hit it with a heat gun or really hot hair dryer to help the leather soak up this really thick paste and set the diamonds in the grain.

I used this to buff out the scratches on my Vivoactive 4 smart watches crystal. It was scratched up pretty good and this made it allmost like new.

This is really good lapping compound at a fair price.

Not really impressed. Spend the money on the venev compound sampler and choose the grits you need. Grit rating is way off. Much less coarse than what it’s supposed to be.

The media could not be loaded.  Have tried cheaper brands. This brand is my go to. Reviews mention the paste being hard to push out. Just hold the tunes in front of a heater or run some hot water over them for a bit. It's thick stuff which is better than being too thin. I use for blade sharpening, but have used a bit for phone screen scratches. Just check what material or coatings you screen or product has before you use these compounds. They are an abrasive. They will polish but at the expense of removing a small layer of what you use it on. Great product!

We put some significant scratches in our stovetop, because we used an incorrect scrubber. Although not like new the diamond grit with a drill mounted wool pad made it look nice. Gradually raising the diamond grit level and scrubbing really helped. I know this product will help you polish glass.
