Gaffer tape leaves residue if you want to remove it later, and looks messy. There's some kind of smooth, rubbery tape that I have seen cables tied together with that was great but I don't know what exactly it is or what it's called. I couldn't un-tape it, but had to cut it off with an exacto knife, but it left no residue and the tape had a nice clean look when on the cables. Anyone know what kind of tape this is?
