Others here have suggested Oxgard as an alternative to Penetrox.
Either one will work on Al-Al connections. But be sure you properly clean
the surfaces before applying the goop. TowerTalk folk have suggested, and I
followed their advice on my tribander, first to scour the mating surfaces
with Scotchbrite pads (Home Despot, Lowe's, etc.), NOT sandpaper. Use one
clean piece to clean the aluminum to a shiny appearance, then apply a THIN
layer of anti-oxidant to both surfaces with the brush that comes with the
jar-size Penetrox, etc. Then work the stuff into the aluminum with another
piece of Scotchbrite. Don't mix the two pieces of Scotchbrite - one is to
remain relatively clean and the other is to stay moist with the Penetrox.
Following this procedure (two separate Scotchbrite pieces) will keep
non-metallic material (oxidized aluminum particles, sand, etc) out of the
joint, and allow for a tight mechanical connection (thin layer of paste.)

Subject: [TowerTalk] TA-53-M
Recently purchased older Mosley TA-53-m withTA-40-KR (40m) kit. I have
disassembled, cleaned up and reassembled the antenna.
1. Does the grounding strap at the center of the 20/40 driven element
attach? Instructions are for 4 different antennas and aren't clear.
2. Instructions recommend use of penatrox at all tubing and trap
connections. Is this necessary and if so is there a substitute product.
I would appreciate any additional suggestions or recommendations.
