Epoxy primers, such as TotalBoat 2-Part Epoxy Primer and Awlgrip 545 Epoxy Primer can be used on items that are made of galvanized steel, but it is very important to prepare the surface according to the epoxy primer's instructions for 'steel' or 'bare steel'. In other words, the galvanized steel must be ground or sanded until it is bare, shiny metal. Follow all directions carefully and thoroughly, and for best results, prime within 1 hour of abrading to a bare, shiny surface.
