of all things, the masonry conditioner primer from PPG works great. (their LoxOn equivalent)

Not a lot of call for us to do galvanized stuff, but we use Sherwin's All Surface Enamel Primer with good results.

any good 100% acrylic should do it really.

We used to wash all sheetmetal flashing etc w/ vinegar and water prior to priming. New sheetmetal usually has oils from manufacturing and machinery in sheetmetal shop. Mineral spirits should do the same.

Agreed, old school vinegar and water on new galvanized..then used to use special primer...glidden galvagrip. Not sure if it's still around, this was several years ago when we did a ski area exposed heat/ac duct system. Gotta get the slick off before any coating. pd

I would not use mineral spirits since it can leave a residue behind that interferes with adhesion of acrylics if it is not left to dry for a while

What are you coating? Sheet metal flashing.. roof? or galvanized Steel?

For steel I would use Galvacon

Sheet metals I would wipe with zylene and prime with zinc oxide.

Cheers
