New Galvanized sheet metal prep and PCing

[bikerdad46]

Hello Everybody
As I stated in the new metal prep post I'm new here

I am looking for the quickest way of powder coating some solar heaters. I know with regular steel sheet metal I would have to blast or dip to remove the mill scale before PCing

What about Galvanized sheet metal. Can you just clean it with denatured alcohol and powder and cure?

I am going to start PCing but if I can land these solar heaters that will mean that I can get a better gun to start with. If not I am going to have to go with something like the H/F gun or that quality (price range) to start. I have done all kinds of painting in the past from brush & roller, airless, to automotive. I am just wanting to help supplement my income a little.
Thanks in advance
