Not if you sand it with dry sand paper. Both ends can be removed so any stray particles are easy to remove. I suppose if you wet sanded it could be a problem. Direct any concerns to notcigs.com before you decide to use any runny, watery, liquids during sanding.
I started off with 400 grit and it barely marked it, but 120 fiber backed paper finally cut the surface down. Even that took over 2 hours to completely cut through the top surface. From there I used finer and finer grit. It turned out pretty bright. The camera kind of shows some etching. I would like to buff it with black, then brown, and finally white bar rouge. That would remove any final scuffing and oxidation. It would glisten like fine metal after that.
