I put tape on my gear to distinguish it from My partners' gear. For quickdraws I put it on the pro end only. I didnt used to do that but then killed a rope in 2 weeks. I am Almost certain it was from a gouged biner. Climb trad long enough and you'll encounter the odd Bolt here and there. If you push yourself you'll eventually fall off a Bolt on a "trad" (or mix) climb.
