Review on Diamond Syringes Polishing Lapping Compound by Dustin Berry

Great item. Polishes metal like no other. I just used this paste on a felt polishing pad on my rotary tool to remove a scratch from a knife blade and in just one step it turned the entire blade into a beautiful mirror. I've made pastes and emulsions down to 0.025 microns (something like 600k+ grit) but I didn't even need to go further. I also use it for a few steps as the roughest to get rid of burrs quickly after sharpening and it does a great job. It is indeed very high in diamond content and is a quality product. I think all of their pastes will be as good or even better and I recommend the high strength (H) but I'm sure the lower strength pastes will still be better than most of the other pastes featured here.
