Galvanizing is great. I had my Bronco frame done when I did my frame off. However, you live in the NE, so its probably a good idea to top-coat it to get as much corrosion resistance as possible. Galv is not a panacea, but its a great start. IF you do top-coat, there are some things that need to be done to get proper adhesion. Just make sure you do some research. Good luck, the build looks awesome thus far.
Cheers!
