I didn't want to raise an old post from the dead, but I thought CeOx really deserves a little more love 'round these parts...

I recently started using the high quality white "Super Cerium" on hard felt after CrOx. About 10-15 laps, and man it is a smooooooth shave. All my razors have gotten the treatment. If you go this route, just make sure it's the pure white kind; the beige/pinkish stuff is less pure and has a higher micron rating.
