The one panel on my truck got screwed up because some metal flakes contaminated it and dissimilar metals cause paint bubbling/oxidation. It happened at the factory and it was not comsidered a defect despite Ford knowing for years of this manufacturing problem.

Yikes! I hope they fixed that issue before my truck rolled down the line. The aluminum body has it's pros and cons. Twice the price of steel to get worked on in a body shop. Yet light weight and better corrosion resistant, assuming no dissimilar metals contact (galvanic corrosion). I have the extended warranty, just in case.

You will probably know around the third year. It happens mostly around the edges of panels. Like the hood edge, quarter panel edges, hatch edges, etc. Looks a lot like the regular cancer you see on metal panels with the paint blistering and bubling. It goes on underneath the paint though.
