I and several others in this area have been using the Flex Seal or something
like that on connectors for 4 or 5 years now. Spray can or paint on both
work
very well. Have had no or heard of any failures or problems using this
stuff.
I now use it on all mechanical points on antennas that have a bolt/nut type
of arrangement. No nuts backing out from vibration etc. If you have to open
up the connector or joint the stuff comes off cleanly.
The best guys in the business can make a bad connector from time to time.
My best advice would be to take your time when doing any connectors. I also
use crimp connectors on all jumpers that are in use indoors. A good quality
tool is essential.
I think someone mentioned before to start with a dry connector and keep it
that way through the process.
Do not use any silicon grease inside any connector for any reason even if
Andrews tells you to. Just do not do it.

Subject: Re: [Elecraft] Proper installation of PL 259's
As far as water proof... no connector not PL 259 crimp or solder are water
proof without doing a good tape job or using some of the spray on rubber
sealant.
Water proofing connector is an art in it own. 3M make some shrink tape that
works good, but now a lot of people are using this spray on rubber sealant
as advertise on TV. So far it looks to be holding up good an can be removed
easy once it setup, it also remain flex able,
If you think water proofing a PL 259 is hard at average ham heights of 30 to
80 feet try waterproofing a N connector on the end of 7/8 " helix at 300 ft
plus feet in the air.
Good Luck all

Having been a Motorola field tech. and shop manager for over 35 years. I
have installed thousands of PL 250's. Motorola back in the mid 1980's start
suggesting installers use crimp on connectors because of too many redoes on
mobile installations. Most of the service problems on new installations was
bad solder connections of PL 259s.
So Motorola developed a nice crimp on PL 259 an a special crimping tool to
go with the connectors. Being an old school tech. I had some reservations
as too how they would hold up in ruff service installations. Well they held
up very well an are still being used today.
So, if you want good crimp on PL259s go to your local Motorola Service Shop
an buy some connector.
