on the other hand
Just to muddy the waters, when I replace the roof vent in a camper, and
asked the RV place where I got the vent whether I should use silicon seal
or something similar around the vent, they said to use the putty tape.
According to them, over time the silicon does not last as well - that is
it sticks to itself ok, but not to whatever it is on.
Of course this doesn't answer your question, it just adds confusion.
Possibly the tape is less messy to work with.:o
