Review: Got deep scratch out of mineral crystal - I had a deep scratch in my mineral crystal, deep enough to cast a shadow on the dial of my watch. It's an inexpensive enough watch that I figured I'd risk trying to get it out rather than sending it for glass replacement. The 3000,5000,14000 grit worked perfectly. I used a dremel tool with the polishing wheel and worked up to the high grit, applying moderate pressure in small circular patterns. DO NOT TAPE YOUR DIAL TO SECTION OFF THE SCRATCH. I did that initially and it caused a "step" from where the tape ended and the compound was contacting the glass. Instead, keep the entire face of the watch uncovered and apply pressure localized at the blemish and fan out applying less pressure as you get further away. With this method I was able to get rid of the scratch and step caused be the lower grit with tape. It took about 30 minutes in total, initially it seems like it wasn't going to work but if you keep at it, it works great. I don't know how well ot would work applying by hand, but with the dremel this was a breeze. Review: The effort you put in. Is what result you get. - The product works. Many light scuffs and a light scratch on my watch. 20 minutes of each paste by hand got rid of all the scuffs and eased the appearance of the scratch. Works well. ## Features - 3-GRIT PROGRESSIVE POLISHING KIT β€” USA-made set of 3 diamond polishing syringes: 4000 grit (2-4 micron), 8000 grit (0-2 micron), 50000 grit (0-0.5 micron).

Is what result you get. *by E***O on 24 September 2023* The product works. Many light scuffs and a light scratch on my watch. 20 minutes of each paste by hand got rid of all the scuffs and eased the appearance of the scratch. Works well. ### ⭐⭐⭐⭐⭐ Mirror like finish on Epoxy Resin *by M***N on 30 April 2024* The 4000, 8000, and 50000 combo worked perfectly on my Epoxy project. The original finish had a few bubbles at the top. I sanded first with 50, 250, 1000, 3000, 5000, and 10000 grit sandpaper. Then, I used a wool buffing pad and a medium to high-speed drill with the 4000, 8000, and 50000 grit diamond polish compound. I switched out pads for all 3 grit polishes. I think the 8000 was good, but the 50000 gave it a clear glass look. The only con is that the portions are small, but my project was small, so it was just enough. I definitely recommend this for small Epoxy projects. ## Frequently Bought Together - TechDiamondTools Kit of 3 Diamond Polishing Compound Polishing Paste USA Made 4000 8000 50000 Grit for Marble Glass Metal Rock Jewelry Resin Silver Gemstone with 10% of Diamond Powder - TechDiamondTools Diamond Polishing Compound Polishing Paste USA Made 100,000 Grit 0-0.25 Micron for Marble Glass Metal Rock Jewelry Resin Silver Chrome Gemstone with High Concentration Diamond Powder - 100PCS Polishing Buffing Wheel for Dremel Polishing Kit, Polishing Wheel for Dremel Tool Accessories, with 1/8" Shank for Dremel Buffing Wheels --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/405302476-techdiamondtools-diamond-polishing-paste-kit-3-grits-4000-8000-50000](https://www.desertcart.co.za/products/405302476-techdiamondtools-diamond-polishing-paste-kit-3-grits-4000-8000-50000) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-28*
