I read somewhere that said duct tape is good for a lot of things; however, one of the worst is sealing ducts. Personal experience confirms this; awful choice for that application. Plus, when you pull old stuff off the stench is awful. The glue from old duct tape smells awful after it has been on a duct for 10 or more years. It has a very sickly sweet smell that you won't forget for a long time no matter how hard you try.All I can say is Duck Brand duct tape is terrible stuff. I wouldn't even use it for what it's for, sealing ductwork...
The cloth "duck tape" was a different kind of tape that pre-dated duct tape."duck" tape got its name, not for sealing ducts, but for the cotton duck cloth was made from. "Duct Tape" is a mis-pronunciation.
Tape used to seal ducts are usually metallic.
I didn't know about the thin rolls, will have find one. I am always ripping sections of the wide tape in half.Gorilla also comes in 1 inch wide rolls that are super handy. I keep one in my camera bag. Duck brand tape is useful for different reasons. I find it is one of the thinnest "duct tapes" out there and is really good where conformability, weight, and thinness are factors.
Sheer grab-strength goes to mil-spec 100mph (Polyken 231) tape... That stuff is STICKY, though.
