No opinion on what Ford uses, or where it comes from, but there are certain steel grades that form a protective oxidation coating (rust) which then protects the underlying steel. Corten Steel (Trade Mark) comes to mind, but there are others. Many of the more recent structural steel members used on highway overpasses are made of this stuff, mostly the curved portions. Reduces maintenance cost (painting).
Aluminum and stainless steel both form oxidized outer coatings when exposed to the air. It just doesn’t look like rust.
EDIT for the record from corten.com: U.S. Steel holds the registered trademark on the name COR-TEN. COR-TEN refers to corrosion resistance and tensile strength. USS sold its discrete plate business to International Steel Group, USS still sells branded material in strip-mill plate and sheet forms. So to get back to your question, no, COR-TEN is not available. What is available is steel in an ASTM A606-4, A588, and A847 finish. If somebody tells you that they are supplying you COR-TEN they are almost certainly unaware of their own product. When someone needs COR-TEN they are usually referring to A606 Type 4, A588, or A847.
