Aluminum + Corrosion-

[omar millmech]

Used to be involved with fire trucks with aluminum cabs; guess what- road chemicals corrode that, also.  There was also a lawsuit about Aluminum body parts of the Range Rover corroding.  Aside- dunno about the new ones, but the earlier Range Rovers had a steel shell with aluminum outsides.  The earlier REAL Land-Rovers had sluminum/duralumin body, except for the cowl area.  Frame metal wasn't too thick, though.  Steel in the frame change somehow for the worse ~1962.
