Wow!!! That's awful.  As Paul N6FEG would say, "Must have been found at low tide".    Mike, W6MAB

But I think Roy Morgan's earlier observation about the environment was the most accurate assessment - if it ain't wickedly wet or continuously high humidity, then it won't be much to worry about.  If your environment looks like that for the set below, then okay - probably needs another design.
