Well, there's duct tape and then there's duct tape. The weathered pictures from the link make it look like the clear tape still has a woven mesh in it. That's a good thing but cuts down the "invisibility" advantage a mite. And that "gooey white muck" is pretty good at filling in irregularities in your wrap job. Of course you might have to wrap a rag around it to keep it off your hands.
But for coolness and holding a bumper on, you can't beat Mil. Spec., dark green, duct tape.
