Not much sticks to TFE.
The Andrews/Heliax waterproofing kits are the best IMO. The sticky
sealant tape may be tight enough to prevent wicking on TFE coax,
especially if the 2" wide electrical tape is used to compress it as per
instructions. It works great on Heliax and DIN connectors so it
conforms well.

Another advice from Andrew, preheat the connectors prior to placing the
adhesive lined heat shrink. Particularly important on big Heliax
connectors but I do it on PL259's and the adhesive really sticks then to
the body.
Rather than invent marginal waterproofing, why not use what is proven in
many thousands of commercial installations? Last I bought the kits were
about $17 and will do a dozen UHF connections. on ebay for $12 - $20.

The answer for the hot melt glue not adhering is simple foreign material. A
fingerprint, lube used to flood connectors, or just plain skin oil/sweat
will prevent hot melt glue, or tape from forming a good mechanical
connection. This is a place where cleanliness is important.
For good adhesion whether tape or hot melt glue, the connectors and coax
must be clean. The tape and/or the hot melt glue must adhere with no voids
