aluminum doesn't rust. but it is a very reactive metal. the thing that keeps it bright and shiny is the fact that it's so reactive; the instant you expose bare aluminum to air it forms a thin coating of (transparent) aluminum oxide on the surface, a process called passivation.
on the other hand, if it's touching a dissimilar metal (like iron,) that reactivity means it will corrode fast if it gets wet. the general assumption on these Mustang hoods is that the seams were contaminated by iron/steel, and as water/salt seeps in there it kicks off galvanic corrosion.

they tested them in some pretty harsh places before launch, but we will see how they work in the salt belt

I believe the Mustang's hoods have been made by an external supplier, while Ford stamps the F-150 body panels themselves at Dearborn Stamping. they talked at length about what they did to "decontaminate" the stamping plant and body shop prior to launching the truck.

Ford should have made a deal with an aftermarket fiberglass hood company and gave those of us who have had the issue, a new fiberglass hood. When I got mine fixed, the rep told me that the only cure would be a fiberglass hood. Another Ford aluminum hood is not the answer unless they totally revamped the way they were made.
