> I asked that question of the British crankup manufacturers, but they
only use stainless steel for locations like harbor walls that are
directly exposed to the sea. For all other locations (including "salty
air environments" like this QTH) they recommend galvanized steel with
heavy waterproof grease.
What I've learned is that you don't want to use a heavy grease because
it traps water and contaminants and will cause the cable to rust from the
inside out. Also the grease will attract particulates and the grease will
turn out to be somewhat abrasive.
