In my experience, the strongest, stickiest tape out there is the ';Gorilla Tape'; brand of duct tape, sold in the big box stores. However, I have only seen it in 2'; width, so you would have to cut it down to the width you need.What is the heaviest kind of adhesive tape?
There is a lead tape that is about as heavy as you're going to get.
Try Gorilla tape, just don't use it on a painted surfaces. When removed, it will take the paint with it.
