Jim,
Yes, I think that is the correct description. I never could remember
the Scotch number. It is superior to using coax seal and comes off
with a simple slice of a razor knife. Scotch-70 is very
expensive. Scotch-88 is OK but Scotch-33+ seems more flexible in
cold temps. Tywrap idea good. I used them in general for securing cables.
Thomas&Betts brand "Tywrap" copyrighted name are the only plastic
ties found to survive -50F temps without breaking. The cheap brands
just snap in temps of about zero F. If running heavy cable runs then
using tywraps with a metal band is better. But must be cushioned to
keep metal from digging into cable insulation.
Those of us that have worked professionally in AK know these details
and learned there are no shortcuts.

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+.
