I've done the rattle can of Hammertite Rustproof, full prep and taken down to the metal before staring.. twice to try to get it right. Then changed the color and had them blasted then powdercoated. What a waste of time with the rattlecans!
I'm "cheap as chips", So I thought the spray and work would have been better. I was completely wrong. Go Powdercoat!
