Doug,
I've done a couple of old Campy seatposts that had insertion marks and corrosion. I dry sanded them with something like 400 grit wet/dry paper. I wrapped the paper around the post and then twisted (rotated) the post back and forth as I tightly gripped the sand paper (I had the seat attached to the post, which provided a lever to help with the twisting). I used the twisting motion to try to retain/simulate the lathe turning marks that the Campy posts have. I took my time; it took a lot of twisting. I didn't go finer than 400 because that would tend to eliminate the "turning marks." I did use aluminum polish (Mothers') after sanding, however. Turned out quite nicely. Might want to use some wax as a final step to ward off corrosion.

Howdy folks.
I have a well used Campy seatpost that I want to make as presentable as possible. I am thinking that I should carefully file out the gouges as best I can above the min. line, then wet sand with say 400 grit followed by something finer and then metal polish. Does that sound about right? Is there a best way to do this? This post isn't particularly valuable, but I have it and it is correct for the rest of the parts.
Thanks,
