My two cents worth:
Professionally, I used a layer of Scotch-70 self-fusing tape covered
by two layers of Scoth-33+ black electric tape. This was on coax
cable connectors on small vessels that were in salt-water
exposure. Removing 5-years afterward, connectors were still
bright,dry, and looking like new.
Scotch-70 is expensive (I paid $30 per roll over ten years ago for
it). But when you got guys on board a 26-foot boat in the North
Pacific with very high seas (like 30-foot) you want their Marine Radio to work.
At home, I use heat shrink with two layers of Scotch-33+ fairly
reliably. If things are too close to wrap with tape then a layer of
Scotch-Kote seals heat shrink, thoroughly.
I don't use sticky, messy stuff like Coax Seal. Scotch-70 molds into
a seamless covering and slits easily with a razor knife.
Some large coax connectors are supplied with heat shrink that has a
melted inner "goo" which is very good sealant. I've found removal is
not messy so apparently the "goo" cures in some manner. Pretty sure
you can buy it at commercial electrical suppliers (but probably in
4-foot chunks which will cost you). I buy my ordinary heat shrink
and tywraps (Thomas & Betts) from a local commercial electrical supply house.
When temperatures dip to -30F the cheap stuff gets brittle and
breaks. That's not when I want to climb a tower.
