if the root cause is iron contamination as has been said, then water contributes. Simply sticking aluminum and iron together won't cause corrosion without an electrolyte. When water comes in (especially salt water) the two dissimilar metals generate a tiny voltage which erodes the more reactive aluminum.

If some mercury were to get on that exposed, oxidizing aluminum, a perforation is almost guaranteed; it's amazing how much of that stuff is in the atmosphere just waiting to attack exposed non-ferrous metals such as the hood on a Mustang.

My 06 GT did it 24K mile summer driven car never seen rain or snow spent its entire life in a heated garage in western Colorado. Part of the problem starts in the manufacture process of the aluminum its self and the prep for paint process at Ford.
