John et all,
I just recabled my tower the past week. I found that the 5 year old
(perhaps older) stainless steel cable
showed signs of slight rust on the coiled up rounds on the drum of the
winch.
I was hoping that the prelube will prevent the corrosion on that part
of the cable. I don't know if the polymer coat will stay intact on the
exposed run of the cables.
