Another commonly-overlooked problem with Al is the bi-metal joint.  On all
ships I've been on, the joint where the aluminum superstructure and steel hull
were joined was a continuing maintenance problem.  Due to the availiability of
salt air (!) electrolysis rapidly destroyed the nearby aluminum, and the "fix"
was to cut out sections and replace with new aluminum plate.  Some sections
were replaced almost every maintenance period.
