one thing about galvanizing - welding becomes...'dangerous'... - good call on 'primer/paint'.
Another thing - rust converter. After 7 years I'm going over my own trucks' frame again, which back then was cleaned (but not blasted), primered with Rustoleum rusty metal primer and painted. Now it has some surface rust showing up...but I'm taking 'advantage' of the rust and using the rust converters out there (Rustoleum and Locktite) to chemically convert it to something more stable, and then paint. I dunno, but from a long-term 'rust-prevention' standpoint...hell it may actually may be beneficial to let the frame rust (or the fresh floor panels or crossmembers or...), and then convert them. I'm giving my frame a very rough sanding and applying Rustoleum rust converter, then Rustoleum oil-based satin black top coat...and time will tell if doing this 'chemical' method will pan out.
