LOL Awesome information there! The Ryobi compound is actually black, but it says 1-3 microns on the side, as well as "for use when coarse buffing, removing rust, scratches, burrs, and pitts from hard metals." That would seem a little contradictory given its grit, but that's what I chose when I bought my piece of wood. Later I found myself at sears, so I picked up the green which is what I was looking for in the first place. White and pink seem like more than I want to get into. Black and green are the levels I was going for. The green rouge doesn't have any grit description on the packaging. It says it is for color buffing and light cleaning on all classes of metals. Maybe my colors/grits are backwards. I'd really rather pick these up locally. I can tell you that the craftsman compounds are about half as expensive as the Ryobi. I guess I could try Lowes and see what they have as well. Here's a link to Ryobi's compounds.
