It's a bit different. The scouring pads should just be plain nylon, which in and of itself could certainly affect the finish of the titanium, but it would take forever. The other kind should have abrasives mixed into the nylon, which would speed up the process, but still takes a while simply because it's not pure abrasive like sandpaper, but often makes for a more beautiful finish because of it, and doesn't remove as much unnecessary material.
I'm just wondering how you're going to get into those hard-to-reach areas like the texture cut into the titanium handles. Sounds like something I might want to try with my zaan once I get my belt sander, but again I'm curious about those little crevices in the ti. Seems like an even bigger issue if the goal is to keep in one direction, but I suppose it wouldn't look too bad if only the flat parts were satin finished.
