I recently saw "duct tape" in some catalog or other, and a close inspection
of the photo revealed that the package carried a "not for use on air ducts"

This is all actually a bit silly, because true duct tape is not what you
want for (e.g.) taping people to the wall on board a spacecraft.  What you
use for that is more properly called gaffer's tape.  It looks the same,
but the adhesive is different:  true duct tape has a permanent adhesive
which is formulated not to come off, ever -- meaning that if you do try to
remove it, you get a sticky mess -- while gaffer's tape has a less
tenacious adhesive that will come off cleanly.  90%+ of what is now sold
as duct tape is really gaffer's tape.

It would appear, alas, that we're seeing a change in the meaning of the
phrase -- the incorrect usage having become quite well established -- and
a new name will have to be found for the stuff which *is* meant for air
