TechDiamondTools Kit of 3 Diamond Lapping Paste Polishing Compound USA Made 600 1050 1500 Grit Lapping Compound for Rock Glass Metal Jewelry Resin Marble with High Concentration of Diamond Powder

400 and 600 were used to help break in and seat rings in a rifle gas block that had a draggy and catchy feeling while depressing the piston. A little dab of 400 and working the piston a dozen times, clean and repeat with 600, then clean and lube created a smooth non catchy feel while operating the piston manually. Choose the right grits for your application and watch how quickly these premium blends get results!!

Originally purchased the set of 3 compounds (5k, 14k, 50k) for polishing harder rocks and gemstones like agate and jasper. Works great for that using it on a cotton or felt buffing wheel on a rotary tool. After I ran out of gems to polish, I moved on to other things that are hard to polish with other compounds: scratched up eyeglasses (you'd need a coarser compound than the 5k to easily buff out large scratches but these grits still totally remove any haziness and make them usable again). The stainless kitchen sink: now it's too shiny to look at in direct sunlight. The bathroom fixtures: gleaming. I put some on leather for stropping knives and tools and it works perfectly for that application, both faster to sharpen and much less messy than wax compounds. The grease-based compound isn't difficult to clean off surfaces with a little detergent or alcohol and a little dollop goes a looong way before it quits polishing: your polishing cloth will get too dirty to use long before it quits polishing. Speaking of polishing cloths, I've found that cotton face cleaning pads are ideal for polishing small things, as are blue shop towels. For larger things or metal, a piece of scrap leather like suede or a chamois is more aggressive. It's also important to note that it's essential to clean the surface and change applicators between grits so as to not contaminate the finer compound with residue from the coarse compound, if you really want a super shine. The 50,000 compound quickly makes a clear mirror on steel if you do it properly. I'll definitely be ordering the higher grits to see how shiny I can get some things and the coarser compound as well. As for the brand itself? Good deal for USA-made products, definitely concentrated enough that you get more than your money's worth. Glad I tried this first before buying one of the "dime a dozen" brands that are listed everywhere.

This is a really good easy-spreading diamond stropping compound. This is American Made goodness right here and I have used this to put mirror-polished edges on several knives. This even worked to rehabilitate and knife I had previously abandoned becuase I could not get it to take an edge. So this worked to put an edge on a knife that was otherwise useless and was ready to be discarded. I paired this with leeather strops from Sharpal, Bacher, BeaverCraft, and TSPROF and have used the different strops for differnt grit of compound so as to have different levels of grit to graduate to. They all took this compound well. I suggest conditioning the leather ahead of time before adding the stropping compound. I have found that rubbing the compound in evenly and letting it dry for a few minutes has yielded best results. Also, a little goes a long way so very little is used and this lasts a long time. after the initial Even coating distribution a dab every 10th sharpening has been my pattern. That may vary depending on what you are sharpening and how many passes you make.

Grit worked well on my transmission cone. Amount in the syringe was just enough!

I’ve used this to polish several distressed knives. A friend gave me a much neglected case folder. I was able to bring it back to usable and decent condition using this product.
