Review: After months of trying to find a true working diamond paste, I finally decided to try TechDiamondTools. The pricing was great and quite frankly the cheap diamond paste was just not working for me (yeah...i tried to go cheap). I've been trying to find a reliable way to get scratches out of mineral glass and most internet searches claimed it was very difficult. Not only could I not find a guide to do this, but couldn't find a grit guide to use for mineral glass. The first thing I did was message the TechDiamondTools and asked for guidance. They replied to me several times and have been very courteous and helpful. They recommended several grits to try, so I went ahead and ordered. Here is what I used, and it works GREAT! Just be patient (this is the key to perfection). Rotary Tool (Cheap) I also used an adjustable speed control rotary tool with 3/32 pro bits compatible that is used for nail manicures. It's electric. I did a search on desertcart and the no longer sell it, but Pinkiou looks similar and it's cheap. I don't recommend using a high speed Dremel. I have one and it goes way to fast. I started with 600, then 1,500, 3,000, and finally 5,000 grit. The results were amazing! Now to keep things in perspective, I did mess up and used sandpaper on one of my other watches. Used 100 grit and that was a mistake. The pictures I posted, I didn't use sandpaper. On the other watch, it did get all the scratches the sandpaper made, however it took a bit more of time. Next time I'm using 2,000/1,500 grit sandpaper. I've read that's what should be used before using diamond paste. I currently have a 14,000 grit that I can't decide whether to use for polishing since the 5,000 did a superb job. I may just return that 14,000 and use the 8,000 for final polishing. Okay, back to the watch. the pictures are the result so the diamond paste. I "wish" that I had a picture of the watch before I even started, but I totally forgot to take some. The pictures are after I had already gone through using the 600 grit and the 1500 grit. As you can see the scratches I circled. Trust me before I started, these scratches were pretty bad. You could actually catch you fingernail on it. Not just a hairline scratch either. The final picture is the finished product, although it looks superb and flawless, I wonder what a final polish with 8,000 or 14,000 would do. I haven't tried that yet. Anyway, I am very pleased with DiamondTechTools, they actually worked with me to replace the 400 grit because it seemed watered down, but they made it right. As a hobby I work on Casio's digital watches and refurbish them, and the biggest problem with refurbishing is the scratches on the glass. Well to end this, I'd like to say I did order the 400 grit paste and will start with that to see if it cuts back on my time. The pictures of the watch I posted took me about 3 hours to get the scratches out, I'm hoping with 400 grit, I'm able to cut that time in half. I don't like to used sand paper, but I will if there are a lot of bad scratches, then I will. Just don't use 100 grit like I did. Use 2,000 or 1,500. I'd also like to say, if you use this process, your result may vary. I want to say that because I'm a very meticulous person and I take my time. I'm only putting this out because this actually worked for me after all failed attempts with other diamond paste, and no I didn't get any free products from TechDiamondTools. If desertcart lets me, since I ordered like 6 syringes of different grits, I want to post more pictures of scratched up watches and the results. Hope this helps folks out there that have not found any documents on getting scratches out of mineral glass, because there really isn't any clear document that outline this. Hope this help those watch enthusiast out there!! And thank you DiamondTechTools, ya'll are awesome and keep making those American Products GREAT!!!

## Questions & Answers

**Q: Would this work well for an iphone with light scratches on a small corner of the screen? iPhone 11 Pro**
A: Hi, for light scratches, use a kit of 2k+4k+8k+50k (or just 4k+8k+50k for very light scratches) Grit pastes. For deep scratches, trying to remove them is not screen functionality safe. However, the same kit will help to make those scratches less noticeable.

**Q: What kind of oil do you use? Can I use this on a leather strop?**
A: We use oleic acid. But if you need to loosen the compound up, you can add practically any machine or motor oil to it. Yes, it can be used both on leather strop/cloth and on wool cloth.

**Q: What is the significance of the concentration? Wouldn't the grit be the same regardless of how much powder is in the compound?**
A: From my understanding, it would be like 100 grit sandpaper with only part of the sand on it. Yes, it's still 100 grit, but there isn't as many granules of sand, which would make you use more and it would take longer. 
     This paste worked extremely well on polishing my tungsten carbide ring.

**Q: how would you load a leather stope with this?**
A: I'm not sure if I'll get this right, but I'd dispense a fair amount onto the strop and rub it in evenly. This is an oil paste , so you should get an even coating.
