It's not a conductive filler. It's an insulator. The idea is to fill
all the voids with silicone goop (which doesn't cure.. it's a thick
grease)to keep water and other stuff out, and to avoid air bubbles.
It's a sort of specialized thing for unusual environments (high
altitude, underwater) or unusual applications (HV). I wouldn't think
that most amateur applications would need it.
BTW, the stuff is basically impossible to remove completely, so don't
get any on anything you hope to later glue to. I think hexane will
remove, but maybe not.. it's pretty chemically inert. (that's why they
use it in stuff that's going to be implanted in your body and in food
