I have had conversations with W3LPL and others (mechanical engineers) about
that comment - and we all agree that we have never had a problem with SS-30.
The AL to AL joints are clean even after 20 plus years - perfect. I think
SS-30 might be a problem with dissimilar metals or highly corrosive
environments.
I can also tell you that major cell phone carriers (one of which I worked at
in the past) - are all using SS-30 for their site builds. They stopped using
Penetrox long ago.
If SS-30 wasn't the best - I wouldn't have used it on the 50 plus antennas
here at K3LR.

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.
