[TowerTalk] Al-to-Al

[Keith Dutson]

Noalox is good stuff.  I recently disassembled a Force 12 C-3S that was put in service many years ago.  Only one joint had to be heated with a propane torch to get it freed.  The other joints came apart using only two hands.

We’ve tried pretty much everything in our salt air environment of South Florida. Most here use Noalux successfully over the past 30+ years.
