If your thinking of buying a new Super Duty

I suspect that the aluminum used on vehicles are a different alloy than those uses on airplanes. May also be true with past aluminum that some claim to not have had trouble with. It may be all about the different alloys available. I suspect in time it will be all worked out but does not change the fact that there is considerable issues with the present materials.

With today's chemistry I don't under how a coating has not been found to solve the issue.
