Looks like Coband/self adhesive bandage. He's got some good colors. I always tucked the end under my last couple wraps when I used it because it seemed to come loose. I guess I wrap weird though. I usually use one piece wrapping from top to bottom slightly overlapping. I switched to silicone tape because coband seemed to absorb some slime/smell
I think you are right, I had to look up Coban, but it does look like it might be the same stuff. It’s thin and very stretchy, but tough, like it didn’t feel like it wanted to tear when putting it on. I stretched it pretty good, used a couple pieces 8” or so, and it is holding the reel on rock solid. I could see where it might absorb some smell/slime like you said, I’d think with its rough surface, it would be impossible to clean if needed. I’ll see how it goes, if I have to re-wrap it a couple times a season to keep it clean, not the worst thing in the world
