Doesn't zinc plating get eaten away by electrolytes over time? Just something I remember hearing in some video about cars. Don't know much about that stuff.
Also, something I remembered watching, was this video by Jay Leno about rust preventative paint by PRO15. Did a bit of searching and ordered this:

It's supposed to be good for that kind of stuff.
