I would prime for sure but not all primers will work. I'd use an etching primer like DP50 from PPG. A standard auto primer from a rattle can is not going to prevent moisture from migrating to the metal.
I would also recommend a product called Zero Rust. It can be used as a primer or as the finish. It has done an excellent job for me at preventing rust from re-occuring. They have a website and you could also check out www.autorestorer.com. They have lots of info.
