Diamond Paste Polishing and Lapping Compound Kit, 6 Pack, 450-80,000 Grit

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.

Glad I went with this instead of polywatch which cost 30 dollars. I have a mineral crystal watch with scratches and cloudy surface which I made the mistake of polishing it with toothpaste as some internet life hack suggests and made it even more cloudy. After some shopping around, I decided to go with this product and give it a try before buying the polywatch since this product is much cheaper. I polished the crystal starting with 1500 then 6000 grits using microfiber cloth with this product and was already amazed by how much improvement I am seeing on the watch's crystal. By 15000 grits, it already have a mirror finish with the cloudiness already gone, any grits beyond that is pretty much over kill. I high recommend this product, this is perhaps the first product I purchased on amazon that work as advertised and I am very happy with with 0 buyer remorse. The only down side i can say is I did not expect the metal of my watch to have a mirror finish as well which changed my watch's original aesthetic, so be sure to use a masking tape on any area you don't want polished. Also, wear a glove, this thing is really hard to get off your skin.

This stuff worked great for my Scratched G-Shock glass screen. I started with the 450 paste using a dremel and cloth polishing wheel. I spent about 45 minutes on that grit and didn’t see much progress. Not sure why. I was about to give up then on a whim decided to jump to 6000 and in about 5 minutes the scratches were gone. I was shocked. It looked great at that point but went ahead and finished it off with a couple of the higher grits. Make sure you clean between grits very well and use different buffing wheels as you go. Highly recommended.

I used it to polish cultured marble sink. Brought to a beautiful shine, but won’t remove scratches. Overall I’m pleased

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.

Horrible instructions, mediocre packaging. None of the grits worked on my watch crystal, but the 6,000 grit did take a scratch out of a window.

Great product just make sure you know how to use it

If you follow proper instructions & sound technique you’ll get the EXACT RESULTS you’re looking for!

Buen producto pero es recomendable comprar también alguna máquina para pulir

I have been useing this on opal. And its comeing out amazing. I highly recommend you do what ever method your doing to shape. Then start at the lowest grit. Clean off the deep scratches. You may need to do this a few times. I know i had to do this do to the odd little deep scratch. But then go up the grits from there. I have been getting glass shines and they look amazing.

By hand, I was able to bring back three watch crystals from scratched (one very heavily and deeply scratched) to near brand-new condition. I'm very impressed with these diamond polishes, very impressed - they work! Unfortunately, I've used up the 450 and 1500 grit tubes, so have to buy another. The cost/benefit ratio is excellent, though!

Using it to polish cabachons, it is working great! Will buy again, thank you

This product removed about 50% of the moderate scratch marks after I spent about 40 minutes polish time. I give 4 stars as the product does help removing scratches. However, it is not easy. It does take much patience, tool, skills and time to get the desired result. I partly blame the fact that I try to remove scratch marks on a piece of Corning® Gorilla® Glass 3 on my smartwatch. Such glass is scratch resistant and therefore also hard to polish. You need an electric rotary tool or a spin scrubber for sure. I do not believe elbow grease will get you there. I use a 450rpm spin scrubber with a thin foam supported cloth pad for the job. If you are working on a smartwatch, it is important to make the pad wet to lower the temperature. Otherwise high heat will damage the electronics on your touchscreen. Using the 450 grit compound, I polished 5 times x 5 minutes. After each 5 minutes I cleaned the surface and check the result. Such a break is also needed to cool down the glass before the next polish. During each 5-minute polish, I have to apply pressure. I then use 1500 grit compound to polish another 2 x 5 minutes. At this point, the original marks have become 70% invisible. Even if I do not move up from 1,500 grit to 80,000 grit, the glass surface is not at all hazy and it is very smooth and shiny already. I am not 100% sure if I can get the marks 100% gone if I spend another 40 - 60 minutes polish time. I need to find time to work on it later.
