Re: Tape for duct work?
I think duct tape was originally made for ducts, but it turned out not to work very well. The heat causes the adhesive to dry out and fail.

Another option that's even more durable than the foil tape is duct mastic. It comes in a bucket and is about the consistency of peanut butter (creamy, not crunchy). To apply it to the duct joints, you can use a brush or don some disposable latex or nitrile exam gloves and smear it on with your hands.
