Most compounds are designed to work under a LOT of compression, not just a
tiny bit. Thicker greases simply won't move out of the way easily, and you
could compromise conductor contact area (which is much smaller than you
think anyway, since the contact surfaces are hard materials).
I'd keep all the "snot" out of the connector, it simply does not belong
there. It will do more long term harm than good. The only thing that works,
long term, is a very light coating of low viscosity pure silicon and only
then to prevent thread seizing. DON'T use it on the center conductor, and
NEVER get it on the dielectric surfaces.
