[50mhz] cushcraft question

[jeremy-ca]

Stop knocking CC if you dont understand the issue.

Galling is common with stainless steel hardware. The coating compound 
procedure has been around for deacdes, nothing new. Several antenna 
companies even include a small tube of it.

Ive been using Penetrox for about 30 years, buy it at electrical supply 
houses.
