I think most of us with older towers have, at one time or another,
painted or at least removed rust starting on the outside leg of a tower,
and repainted it.
Has anyone done anything to the inside of the leg?
The reason I ask is because I'm sitting here in my office this morning,
with the scanner on, listening to a guy tell other hams how he removed
the top plate, and poured a sealant down the tubing, (American Tower,
like a Rohn 25), which is to keep it from rusting from the inside out.
In my 50 years of working with this stuff, I don't recall anyone talking
about something like this.
