Its not shrinkwrap,its Decking tape.Used on smooth boat decks to make them non slip.There is a few different types,some are like sandpaper.
I have used it and it comes on a roll 1 inch wide and is applied in a spiral on the butt.
I got mine from a ships chandlers in Gateshead,but that was around 10 years ago.
The cross weave shrinkwrap gives better grip..
