That was me. This works great, but go easy on it and don't use anything rougher than 220. Then some 000 steel wool to buff it a little will make the playing surface MUCH more playable. You don't want to have any sanding marks. When I did it, I sanded to roughly mimic the surface of the Tornado. If it's a Tornado or equivalent (oooo, is there an equivalent?) I wouldn't mess with it at all. Just leave it and maybe clean and rough up the balls, so to speak, if they're that bad.
