Rottenstone and pumice are only slightly less hard than silica based abrasives (or converted silica types like novaculite).

4F is less fine than finer abrasives that we're used to, you might find that you're better off without it on your base stone (but trying if you have it won't hurt anything, you can lap it off if you don't like it).
