I'm up in the Northeast, coastal and salt happy in the winter. The major difference in the picture is the exhaust manifold. Unlike the bolts, the manifold got a nice coating of corriseal before installation when I did the in frame at your house in 2020. Despite some of it burning off on the initial drive home it has clearly resulted in almost no rust buildup on the exhaust manifold. It was an interesting experiment and I think the results speak for themselves. So the bolts were not treated or painted in any way.
