  You don't make it clear, are you referring to silicone sealer
or the silicone grease, that looks like Vaseline grease (petroleum

  I have been filling (to overflowing) all exterior connectors of
all types with the silicone grease (sold as thermal linking for
the mounting power transistors) the type without zinc oxide with
no detectable ill effects. (40 years)  I reuse BNC + "N" and PL259
connectors many times.
 (I never operate over 45 watts, for RF safety reasons)
  I have hundreds of used phenolic insulated PL259's (heavily silver
plated brass amphenol or ITT etc. brands) and I only use (and re-use)
teflon insulated UHF connectors for VHF and UHF installations.
I never tape up connectors, never found any water in any connector,
just the grease I put there.
