hot dip galvanizing

A guy I know has this done often on gates and railings. I think you have the basics right, but there's a fair amount of art involved in doing it right so the zinc stays there. There's a lot of variation in surface finish, too. Then there's the issue of getting paint to stick to the zinc. Auto mfr's have only recently figured that one out. How about using "cold galv"? It is a paint that is supposed to work in "sacrificial mode", like the zinc galvanizing process. It comes in both spray cans and for brush-on application. I think your friendly welding supplier has it.

I used cold-galv and indeed its performance is very impressive.

I use cold and it works - I bought large cans at Lowe's or HD - oversize paint.

I also painted over it - to protect the zinc from acid rain from the air or from the trees. - Yes tannic acid will eat steel and car finishes.

Galvanized fences often rust on the tops of the bars. My weather station pole in concrete is cold and over coated with black. Even the part in the concrete.
