Interesting. I would prefer to use water base if it were just as good - much easier to clean. Do you have any idea why the likes of Kraus has chosen to sell only grease-base? Pretty thick grease at that - it resembles (pure) lanoline in its greasy messiness and reluctance to be cleaned off, but it also has a solvent because it dries out easily.clover...water soluable
Also, I use mine for flatting concave mouthpiece tables....using a sheet of glass as a surface table.I use it for lapping valves, pistons and slides on brass instuments, and use it occasionally on saxes when fitting crook tenons
That's right! Carborundum is the name of a valve lapping paste meant for the purpose of lapping of auto valves to its seat. I have a similar set but in two plastic cans. Much to coarse in its original way to use for a supposed to seal metal - metal surface in any woodwind.Also, I use mine for flatting concave mouthpiece tables....using a sheet of glass as a surface table.
Not a clue as to the name of my carborundum paste....I have always had it, lives in the garage in it's double ended (fine & coarse) little rusty tin....very greasy.
That is the very reason why, after about 30 years, the coarse has never been used...probably designed for lapping in ships' propeller trunnions.That's right!

A wee small voice of my intuition says that the ideal lapping compound for steel may not be ideal for brass. That intuition may be incorrect.That's right!
