        NEW AND OLD CAST IRON
        Blast with a steel grit and degrease before priming. Old cast
        iron is difficult to prepare for a satisfactory bond.  It can absorb
        oil and water soluble contaminants that will keep returning
        to the surface after the coating system has been applied
        and affect the coating system adhesion. An adhesion test is
        recommended prior to starting the project.
