A "putty" product I found and like is from construction: Tacky Tape
from Schnee-Morehead. It is a butyl self amalgamating tape which
conforms like Coax-Seal but is easy to remove. I found it on Amazon
I also use Silicone dielectric grease from the local auto store on SO239
threads only so water has less opportunity to wick in the thread clearance.
I had some water leakage with silicone tape on Belden 9913-F7, I think
because the braid weave "prints" onto the outside of the sheath. Since
there is no adhesive with silicone tape I'm a little suspect of how
water might capillary wick between it and what it is covering. For
outer coverings and a sharp item protection (e.g. cotter pins in
sailboat standing rigging or wire rope crimps) the self amalgamating Si
tape is terrific.
Two lessons from that - stick with Buryflex and use Tacky Tape. I'm not
sure of the UV longevity of T-T so cover it with Scotch 33 to be sure.
