You're on the right track. Krylon has a good zinc-rich galvanize-
appearance paint:

You can also electroplate zinc:

Electroless nickel is another option (see the site above) and may be
more durable than zinc and easier to apply.
In my misspent youth, I worked as a tech in a steel mill and the
continous galvanize line (as well as the tinplate lines) were on my
route. Lots of very nasty hot chemicals (e.g. chromic acid); the
galvanize line used a hydrogen atmosphere...
