Neal,

Junking the thing isn't a bad idea, particularly if
you spy any physical damage.  If the rust is purely superficial,
and cosmetic, rather than structural, then I'd give it a coat of
rustoleum rusty metal primer...followed by your favorite rustoleum
color, and consider that as an end-of-life strategy.
you can touch it up, as needed.  

If there is any hint of structural weakness at any of the overlapping
joints, I would definitely junk it.  That includes pitted rust or any
flakes more than a couple of thousandths thick.  Towers are cheap.
People and medical bills are not.
