Had bad scratch on the AR coating of a sapphire crystal, used all 3 pastes in succession, scratches completely removed and the sapphire looks better than new.

  • Kit works.
Size: 500 800 1200 Grit
Used for one v8 engine. Also one small engine. Grit is good 👍 work's well. Suction cups were fair at best. But get the job done. Probably need new Suction cups next time around.

  • Great polisher
Size: 14000 100000 200000 Grit
I purchased this polisher to remove scratches in my glasses. I've tried baking soda. That made the scratches more pronounced. This polish worked. To achieve the desired result, you have to start with the lowest grit and progress to the highest grit. Once at the highest grit number, you have to polish the glasses repeated over several days. I polished at 200,000 grit for 15 minutes per day for four days. All scratches were gone at the end of the fourth day. This product works as advertised. You can't beat the price either. ... show more

  • These polishing compounds work!
Size: 4000 8000 50000Grit
I used these compounds with the wool cloths to restore two pairs of RayBan sunglasses, both of which were badly scratched. They sell for $260. I kept them for nearly three years in the hope of someday finding a way to make them wearable again. TechDiamond proved to be the solution. It takes a little time but I removed almost all the scratches - the deepest ones remain but are polished and barely visible. ... show more

  • Iffy.
This product seems to gum up and peel off quite a bit. I'm sure you could use it to polish your products, but don't expect to get a lot of use out of it. After a little while the product will ball up and be unusable. At least that was my experience using this item.
