I'm sure.  I was told of this stuff back in my high school and
college days when I was very involved in theater stage lighting.
We had solid state SCR dimmer systems who's control panels were
banks of slide potentiometers.  All you had to do was screwup the
low voltage control lines from them to the dimmer packs (like
short them) and the little slide pots would go pop rather quietly
and stop working.  Spray them inside with LPS-1 (or whatever the
appropriate LPS spray is) and they would work rather well.  The
original range and linearity would be gone but you could get
through a show.  Perhaps the stuff would disolve the burn marks
off of the resistive element and wiper so that the wiper would make
contact again.

Audi content:  When I bought my car new I immediately potted the
backs of all of the electrical connectors that were exposed to the
elements (that is in the engine compartment and underneath the car)
with silicone RTV.  I have never had a problem with connectors or
wires in my car.  Of course, the original fuse box did an admirable
job of protecting the radiator fan and ignition wireing and fuses.
