TechDiamondTools Diamond Polishing Paste Set of 5 Syringes X 5 Grams (L), Polishing Finishing Compound, Sizes 5000 8000 14000 50000 100000 Grit, Mesh - With Light(10%) Concentration of Diamond Powders

Awesome product. I used these polishing compounds for the first time on restoring micro stainless steel inspection mirrors for electronics soldering class 3 work. I was able to restore the mirrors back to 98% reflectivity (there were very deep scratches that could not be restored - keep in mind that I started with 400 grit and worked up to 100,000). Very satisfied and will purchase more in the future.

I have a granite island top that had become very rough in some of the vein imperfections. I cleaned the top then used the water-thin super glue to fill some bad imperfections. I used regular sanding paper on pad with water to smooth out the super glue fillings. This brought to light some imperfections I missed with sanding powder. I cleaned and added more super glue to those areas and repeated the process. After this I first sanded my granite island top with various grit diamond pads up to 8000 grit using a sanding/polishing tool on #1 setting and occasionally spraying on water. Then I began with the 8000 grit polishing paste (without water) applied to wool polishing pad, polishing at #2-3 speed settings on my HF polishing tool. I polished around 10-15 minutes with each grit then cleaned the surface with soap and water between each grit. I polished using 8000, 14,000, 50,000, 100,000 and 200,000 grits and the counter looks like new after final cleaning. (Note of caution: For testing the complete sanding/polishing process, I used an old quartz top which had been cracked due to a hot griddle being left on too long. I had sealed the crack with super glue. When using the polishing compound on wool pads the surface got too hot and the crack popped open again. Be careful to allow cool down between each grit on quartz to prevent any tendency for quartz to crack!!)

Stuffs works great! If you pair it with a dermal tool with a cloth wheel you are really cooking. Everything this polish touches shines, gets all the micro scratches out of my wedding ring I scratch up from work. I like how you can keep stepping up the grit to improve the finish even more. It's almost addictive using this stuff, I wanna see how shiny I can get things ahahahh.

I mostly liked that you don't need a lot of paste to get an awesome polish. I ordered the wool pads and both combo boxes and also the 200,000 grit single tube and would highly recommend all of it. The only constructive criticism I could say is that the paste syringe can be tricky to eject a small amount. The paste at the end can be not as squeezable as the rest on the tube so as soon as that amount exits the syringe then the rest wants to follow easily. Also, not anything on the product but definitely wear vinyl/layex gloves to not get the paste or plating on your fingers. Overall 9/10 *'s

I bought this set to polish a used watch i purchased. They did the job flawlessly better than expected ! I recommend this set for any DIY guy/girl out there
