Great tip, Tim. I have seen dry Penetrox on old antennas but I assume that
it does not affect the joint's conductivity. Jet Lube SS-30 has excellent
Amazon reviews. I wonder how the following note on the manufacture's website
relates to aluminum tubing antennas, especially those in corrosive
environments: "Not intended for use with aluminum where galvanic corrosion
could be a significant issue".

I used Penetrox for years - noticed that after 10 years or more that the
Penetrox would dry out and turn to a crusty dust. I mentioned that to W3LPL.
Frank said try Jet Lube SS-30 - which is what he uses at his mega station
for all of his antennas.
I have been sold on Jet Lube SS-30 ever since. After 25 years here at K3LR -
the Jet Lube SS-30 comes apart and is clean and offers a great low loss
connection. I use it everywhere hardware and connections are involved (even
in the shack) - as does W3LPL. Do not worry that this is copper based paste
- it works SUPER for Al to Al.
