You may have a different definition of "pro" that others do. Is it just
the broadcast industry that utilizes "pros"? That's another subject for
discussion.
It's true that modern connectors are theoretically weatherproof, and I
do not weatherproof the many 7/16 DIN connectors on my own ham station,
whether they are on Heliax or 3/8" RG8 stuff.
But in my (dare I say it?) professional work, our customers (AT&T,
Verizon, T-Mobile, etc) require it. Until recently it was always
tape-butyl-tape. Nowadays it's custom rubber boots...but still, it's
external weatherproofing.

I'm pretty certain that the pros use butyl mastic
The "pros" don't use anything because they don't use UHF connectors.
They are working with Heliax, waveguide, or ridgid line and the lines
are often pressurized. Connectors made for those kinds of lines don't
require all these wild methods involving tar, and tape and do more
harm than good by sealing in moisture.stevek@jmr.com is correct.
The ideal method is nothing. If you have a feedline run laying on or
under the ground that's subject to flooding, then elevate the
connections. I'd want to do that anyway to make it easier to
troubleshoot. I tried all the tape, tar, grease, and so on a few
times early on and realized it was heading in the wrong direction.
