FinisolvaDiamond Polishing Compound Kit of 6 Polishing Lapping Paste 80,000 to 450 Grit for Glass Watch Marble Metal Resin Rock Jewelry Etc. with High Concentration of Diamond Powder Scratch Remover Repair

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.

Bought some bottles with glass stoppers that were poorly ground. 450 grit lapped them perfectly with a little effort. I'm sure I'll find more uses for the assortment in the future.

Literally magic in the tubes. Can buff out acrylic, mineral and even sapphire crystal.

These work well and have actual grit to them, however the syringe is very brittle and almost all have failed and end up shooting paste from the sides.

The quality is top shelf, and depending on what you are using for,it doesn't take much to get the glass polished look.

Purchased these polishing compounds to polish rocks - and they did a great job, with the exception of the 1500 Grit compound. All of the other compounds work great, but the 1,500 grit feels like it is mostly just oil and requires a much longer polishing time than any of the other grits.Other than that, these are fantastic. Not sure if I got a bad batch or what - but the 1,500 grit sucks.

Excellent product that along with buffing wheel makes my knives shine and removes minor scratches. Recommended.

Works great
