Scratches in mineral glass, Hardlex, saphire, and poly watch crystals have met their match! Very effective, affordable, and high-quality diamond compound pastes in an effective range of grit. The oil-based compound is easy to spread yet keeps where you want it. It (and a handful of dremel-type, cone-shaped buffing bits) took what I thought would be a tedious job to polish a deeply scratched mineral watch crystal into a job completed in mere minutes. So easy, in fact, that kept going and polished every watch crystal and steel case in my household with even a hint of a scratch. I even used the two finest of the grits on some older watches with poly crystals and brought them to a glorious clarity and luster. As a watch enthusiast, this stuff is a game changer. I can’t wait to try it on my knives and cutting tools. One (obvious) hint- In order to work effectively, it’s important to remove all grit/compound prior to moving to a finer grit. With a handful of colored markers, I mark a small patch on each diamond paste label, then colored the top of the corresponding buffing pad/wheel/dremel bit in the same color. It makes cycling grits as easy as wiping down the workpiece with a microfiber cloth and changing dremel bits. Because the pads absorb a bit of compound, this is really the only way to not mix grits without tossing pads after a single use. Read more

Good stuff. Take little time. But end results. Are perfect. The video is of a mold clamp. I was just killing time at work. Pic is 2 mold clamps. For reference. I did use a die grinder and buff pads to get the surface as close to a polish Finnish. And the worked each stage of polish. To get end result. Read more

Works great and a little bit can polish a fairly large area. I used this to restore a 40 year old American Standard china bathroom sink. After decades of use it was very hazy and drab looking. I cleaned the sink then wiped it with Windex. Then used a terry cloth and the 6000 grit to start the process. Just a few dabs. Using a circular motion I polished the area. Then turn the cloth to the clean side and wiped the residue off. Then I repeated that process with 15000, followed by 80000. It is important to move to a clean area of your polishing towel every time you finish with one type of grit. If you use a towel with courser grit residue on it you won't get a fine finish. When I was done I used another clean cloth to polish off all remaining residue. The results were excellent if not better than new! The finish almost resembles glass. I love restoring things like this that might have otherwise gone to the landfill. Plus I save the time, money, and effort to put in a new sink. Very pleased. NOTE: Always practice on another item or in an area that is hidden. Once you see how it works then carefully start on the item you want to polish. I've only used this on a china sink, but pretty sure it would work on similar materials like glass or glazed ceramic that has a haze. Have not tried on metal or other materials yet. The key is to start small and gentle until you see if it's compatible and effective. Keep in mind that this isn't for deep scratches. Deep scratches would need smoothing first. UPDATE: I've now used this on metal and hard plastic and it worked amazing. I don't recommend it for paint or any soft material because the diamond grit might embed leaving a dark area. It is generally best for hard finishes. It works great but always test a sample area before applying to a visible surface. Be careful if using on a plated metal surface or chromed plastic. It could potentially remove the thin plating. Just start out slow and get the feel of how it's working on an item you are polishing. You can wipe off polish residue with a dry clean cloth and use Clear Windex (not the blue or yellow kind) to get it really clean. Read more

Didn’t do much for my project. Glass scratches still there. Will try other products. Edit: The original intent was to use it on a glass scratch. Using the 450 did not make any noticeable difference. The seller contacted me and I decided to try the paste again on another glass with scratches that are less deep. It did work better using a Dremel in low speed for about 30 minutes. The higher grits work well for polishing glass but I would not consider this product for removing scratches- maybe it was not designed for that purpose. Next I will try using cerium oxide or something with a lower grit value, maybe around 100 or 240. Customer service for the company is great and that is appreciated. Read more

I used these on a mosaic piece that included some fused glass. I was given this piece by someone who thought it was trash because there were black pitted spots on white glass. Just assuming I couldn't make the glass look worse, I simply followed the directions and the polishing compound completely removed the black spots. I used the largest grit, a medium, and then the finest grit to polish. It came out beautifully. There were also some scratches on purple glass that this compound successfully removed and polished. I highly recommend it. BTW, I used my rotary tool for a lot of the cleaning and polishing and that made it easier. Read more

Excellent product! I used for polishing resin/plastic jewelry. A little goes a LONG way! Good variety of grits, and tubes are made with snug fitting lids for each nozzle. This gives User total control of amount of product used and prevents the compounds from drying out. Not the old tiny cannister that don't keep product moist and in proper (creamy) condition. The syringe container gives the User total control of application! I used this product with a Dremel, with their soft cotton buffing pads and a layered muslin polishing pad. You can also buff by hand on larger areas. This will be my "Go To" Kit to polish small plastic items (cellphones/resin jewelry) with the ample supply of grit sizes. I'm sure it will preform as well on jewelry (14KT gold and Sterling Silver). Great value for the price! Read more
