I use the tape and like it. I think that a lot of the vinyl camo's have a little glare to them, and the cloth tape has none, and that's important to me. I've done several of my own guns and never taken it off, so I don't know excactly what it leaves behind, I'm a little skeerd to even look.

The gun itself is a tool to me, just like a pipewrench, chainsaw, or hammer. I care more about function than a good quality blued finish.
I've got one that has endured several summers of clay shoots and has definite 'oil spots' from my hands, so If hunting something with a better nose than a goose that is something to think about.
