..electrical tape's properties aren't for "sticking". ..it sticks to itself better. ..electrical tape is used for insulating electrical connections. ..it would pretty much prove to be useless in a repair situation unless you're in my line of work.
..go w/ duct tape. ..there's also gaff tape, which i prefer, that sticks a lot better than duct tape and leaves less residue when removed. ..it is, of course, more expensive, but will stick w/ more force to different surfaces than duct tape.
..then there's there is the 100mph tape.. ..the stuff I've used is kind of like a cross between duct tape and gaffers tape.. ..its got the sticky quality of gaff tape, but the smoothness and less fiberous skin of duct tape..
