This evidently isn't a very common problem because I did a search on the words "rust coil terminals" and only came up with one thread where a guy had the same issue.
I don't believe rust on the coil terminals is common but it probably depends on where you live. I don't have any on my 3 "W" bodies but I'm in the desert Southwest.

I have heard of moisture contamination under the coil packs causing ignition control module (ICM) problems. Arcing may be visible.
