If you're worried about moisture getting into a coaxial feedline, I
wouldn't settle for anything less than Coax-Seal (mastic tape) for a
long-term hi-power installation. Proper installation of the coax-seal
is very important, randomly gooping gunk around won't help much.

Don't worry about exposed connections to/from antenna wire. Just keep
the moisture out of the coax.

If you're feeding with ladder line, I don't think there's anything
that has to be waterproofed at all.

Some people like to spray with clear acrylic to keep things shiny but
I don't think this will hold up forever in the sun, and it does
nothing electrically, and might become a minor pain that you have to
scrape off in case of modification/repair.
