Have ordered this tape more than once. Very strong adhesive. Have used to repair a car floor mat, cracked storage bin, garden hose, and several other items. Holds up well.

Used this on the roof of my car as was having sunroof issues... let me tell you it sticks really well ...didn't break down from the elements. Was extremely hard to remove. If you want it for holding or a possible leaky roof great product.

Didn't stick when my boots got wet! The tape may be waterproof, but the sticky stuff sure isn't! Totally useless because of that!
