Many grits available. Depends entirely on WHY you use it and how rough the surfaces are to begin with. If your need's only to witness; suggest layout dye e.g. DYKEM.
WHY do you need to lap these valves ? Old worn valves-seats ? New ? Verify-Witness only ? I ask, because nowadays, many shops' Cutters produce a much finer surface than grinding Stones aka Rocks. True; I've made a few silk purses from a sow's ear.

Just touching up a valve on a John Deere tractor! I see clover made by Henkel comes in large containers so that route will not happen.Also would like to rebuild my L-82 in the future and being a Gemin I am in to every thing. My interests grow every day in mechanical engineering

Permatex currently markets a small tube of paste that's essentially an equivalent. I see both 1 1/2 oz & 3 oz.
it's labelled Valve Grinding Compound.
*in your deere
? are the valves in head OR in block ?
? will you lap them by hand or with a power tool? The wooden stick hand-tool with a suction cup on either end works good.
