They actually make a heat shrink tubing that has an inner layer on it
that melts at the shrink temperature. You put it over the connector,
zap it with the heat gun, and the goop squirts out the ends as the
tubing shrinks.
There's also a low melting tape (no adhesive) that you wrap around the
thing to be sealed, putting heat shrink over the combination. Same
idea.. you heat the assembly, the tape melts, the outer tubing shrinks,
and you've got a watertight seal.
I've heard stories about people actually sealing leaks in pipes with
this stuff, but not actually seen it done.
