TechDiamondTools Diamond Lapping Paste Polishing Compound USA Made 1050 Grit Mesh 12-20 Microns Lapping Compound for Rock Glass Metal Jewelry Resin Marble with High Concentration of Diamond Powder

The TechDiamondTools Diamond Lapping Paste Polishing Compound boasts a 1050 grit mesh between 12-20 microns, making it effective on various surfaces like rock, metal, glass, and jewelry. Customers have inquired about the product's compatibility for iPhone screens, apple watch scratches, leather strop, and hard water marks from crystal vases - the product seems to be compatible with most surfaces as long as the grit is appropriate for the desired outcome. Customers who have used the product on sterling silver praised the beautiful shine it brought out. One customer used the product on a vintage ring and was happy with the result, while another used it to attempt to remove scratches from a Seiko watch and found it effective in removing light scratches but not the deep ones. The product also gets a shout-out for polishing rocks, knives, bullet feed ramps, and other surfaces. The only downside mentioned is its cost.
