painting galvanized steel


I have a question that's not really RV related but I have noticed a wealth of experience on this site in the year or so I've been a member so here it is. I have to paint the inside of a galvanized cooler here at the brewery and I'm wondering if anyone has experience with painting galvanized steel, it has a lot of white flakey spots that I guess are oxidation of some sort, I'll have to clean these off but is there any special kind of primer or pain for galvanized steel?

Is it painted now? You can wipe it down with vinegar to neutralize the galvanized finish.

Well, I know that Chevrolet never figured out how to do it. I offer my old Astro Van's front deck below the windshield as proof of that inability to make paint stick to galvanized metal.

And much longer before that (somewhere around 1975) I remember the same problem with an old Ford Pinto station wagon.
