Did you perhaps mean Scotch #70 self-fusing silicon rubber tape? I have
used it for years to seal connections, never opened one (after up to 25
years of service) that looked anything other than brand new. Expensive,
but it works like nothing else. When properly installed and
over-wrapped with either Scotch 88 or Scotch 33+, connections become
next to invulnerable. Hint: Put a black ty-wrap over the end(s) of the
over-wrap tape to keep it from working loose in wind and weather.

Just one more comment on this topic:
Ron addressed marine use. My former job of 15-years was working as
lead electronic tech for an oil spill recovery organization whose
primary region of operation is Cook Inlet in southcentral Alaska (200
by 30 mile body of salt water). Electronics installed on boats
ranging from 25-foot to 210-foot provided an excellent outdoor
"laboratory" for testing cables and connections. Anything exposed
would corrode within three years. I sealed coax connectors of all
types by using a gray annealing tape from 3M (Scotch 30, I believe)
which was covered with a double wrap of Scotch-33+.
