So I guess Mr Milton never dropped in on this thread! LOL! Ah well, no problem.
Anyway, it kind of dawned on me recently that I haven't stressed enough the main point of this thread. I present a certain method and the philosophy behind it, of course, and others chimed in with their methods, and I maybe didn't stress enough that this is the point! That there are MANY methods, and the point is that you CAN re-surface and re-pair and work a titanium light like this! Which is so, so cool! Got too many scratches? No worries, there are things you can do! Got a bad ding? Never fear, there's stuff you can try. Titanium is just awesome this way. So no matter what you're approach and philosophy--use a 3M pad, use metal polish, use strips of fine sandpaper, don't do anything at all and appreciate the patina--it all goes to show how great titanium is for making flashlights (among other things!)
