Mine had some surface rust that was wire wheeled off and rust preventative was sprayed into all the cavities. I live in FL and the Expedition has been in my family since new and garaged the majority of its life, so not really one that would have had much rust. Likewise, it's been babied and garaged, never any issues with window or windshield seals. The socket there wasn't quite a careless mechanic, but I'll show the details in another post. They're different. Even things as minor as the mirror turn signals are not wired in on XLTs but they are on EBs. I learned that the hard way and it'll be covered as the build progresses.
