[TowerTalk] why not regalvanize?

[doc]

Question:

Does painting over rust ever really *stop*
the rust or merely cover it over so it
continues to erode and there is an unexpected
failure?

I suppose *in theory* some coating materials
seal things so well that no oxygen can get to
the prior rusting areas thus no further action
may occur -- but *in practice* ??
