On a recent trip the filter threads came loose on my Nikon 18-200, and some of the screws that held it in place where caught in the black sticker that covers them.
I peeled off the sticker, and surprisingly it looks like there was no damage, so I just screwed it all back together. I'm unsure whether I should try to reuse the sticker, or try to find a reasonable replacement; I can't really search for an answer since I have no idea what it's called.
