Carbon and Corrosion

Back in November, I wrote about how carbon frames can't possibly suffer from water and corrosion.  A recent letter to Lennard Zinn of Velonews claims otherwise.  The letter's author claims that carbon against aluminum will eventually cause failure by corrosion but does not say how.  He makes parallels between wind surfing gear and cycling gear.  Well, any aluminum part is going to fail in a marine environement eventually.  There are many aluminum seat posts in carbon frames and no one seems to be snapping off seat posts left and right.  An interesteing article though.
