My Rawland (sacrilege!) sports a used Nitto S-83 seatpost that I got on uber-cheap because it was really badly scratched. I have built up a fair bit of confidence sanding and polishing aluminum parts. I put this part off to the last because it was by far the most scratched. I finally decided I was done working on it. The very deepest scratches are still visible, but only barely. I'm pleased with the results. The laser etched Nitto S-83 logo part is gone now, but honestly I think that's a good thing.
