    Very strong sticky tape. Works great. Buy more then you think because once it sticks to itself it’s nearly impossible to separate. And having good scissors makes a world of difference, but have paint thinner or some kind of goo remover on hand as your scissors will bind after a bit of cutting.

    Love this tape, it is super heavy duty, after I had taped all my seams my crawl got full of water twice and this tape held up all the way…..
