[TowerTalk] Loosening Al tubing to Al Tubing

[John / K4WJ]

Roger, I vaguely remember someone posting on this reflector that when 
using Noalox that after applying it you should run a rag over the area 
to remove most of the bulk and just leave behind a very thin layer of 
Noalox or Penetrox. Why do you say "Use lots of Noalox when reassembling?"
