I have some zirconium oxide, and I like it. I am not sure that it is slower than cerium oxide, in fact, I suspect it's faster. But it does seem to me to be a bit smoother. But it is not as smooth as rouge. Just a few minutes of figuring with rouge, messy as it is, will make a surface much, much smoother than either ZO or cerium oxide, or at least, the varieties I've used.
Though, to be quite honest, I have not done side-by-side double blinded tests to compare all 3.

Salem lists Zirconium Oxide - on their site - as being 0.6u and the old container I have is hand marked "slow polishing". Has anyone used this?
