I would think the risk of marring the surface with rust would outweigh the advantage of protecting it with tape. I have seen a Sako when the tape was unwound off the barrel once, and it had lines of rust around it where moisture had got in under the tape edges. I have rifles with no tape at all with no rust at all, or scratches, so I am not sure what the tape is for. But I dont look down on people who have camo tape. I am a liberal type.
