[TowerTalk] telephone company non-sticky semi-solid stuff

[Jim Lux]

Yes and no.  It isn't sticky or adhesive at all, but, if the object being
wrapped up has too many holes that get filled, it's hard to separate, and
might leave little globs behind.  I don't know how structural the stuff is.
Certainly it works real well on e.g. connectors and soldered connections. We
used to use it on (mated) coax and XLR connectors that were going to be
immersed in water for a relatively short time (few days).
