Yeah, you're restricted to horizontal motion. There's simply no way around that. But...we're talking about a tool that travels in a circle, so in effect, a given square inch is being hit from a lot of different directions. As opposed to the motion of belt sander which travels in a straight line.
Also, you're not going at it with 80 grit. The compound is going to leave a shiny surface. It's gonna work.
