And yet another, another weird corrosion story (not synth related)

[Peter Snow]

Ahhhhh! the good ol' Land Rover. In my mis-spent youth I owned a '52 SWB.  Box section
steel chassis, all aluminium panels,
2 litre, 4 cylinder, slow as molasses.  I never dropped it out of a plane, but that
vehicle would take you up the side of a house in low range 4WD.  
(OK, I'm exagerating about the house, but I loved it!)
