Yes, an epoxy primer such as TotalBoat 2-Part Epoxy Primer, will stick to galvanized steel as long as the surface has been prepared properly, and the epoxy primer is applied within the recommended time window. Surface preparation involves grinding or sanding until the galvanized steel surface is shiny and bare. Remove all sanding/grinding residue, then apply epoxy primer, as directed, within 1 hour of abrading the surface.
