I used this BIG roll right away to seal various metal ducts, angled and straight sections, etc. It holds so well that I didn't need silicone or duct tape or other adhesive to secure the pieces. Very easy to tear off from the roll and then adhere thin strips. Be careful not to let the foil-tape sticky surface touch as you pull it from the roll.
