I use Dow Corning's (Now just Dow Chemical? ... Following merger and buyout)? DC4 dielectric compound.? It is a Silicone grease developed in WWII to seal spark plugs on B17s to prevent arcing at connections at high altitude. It remains a grease (never hardens) EXCEPT when subjected to an arc which causes it to decompose leaving Silicon Dioxide (powdered Quartz) behind as do all brands of Silicon dielectric greases.? It used to be expensive, but with competition the price has come down.
? With Dow buying out Corning's stake it's now just another part of Dow Chemical so I'm not sure what's available.
All their Specialty items including RTVs have become commodities with substantial price reductions.? I retired from DC in 1997 So have little current information.? As I recall, it has an infinite shelf life even after the tube has been opened.
AFAIK all Silicone greases are pretty much the same regardless of who makes it.

I'm talking about the goo that you put in coax connector joins, which
fills the void in the connection and seals out any moisture.
A Google search has come up blank.
