Moeller Zinc Primer Aerosol Spray works great on aluminum surfaces above or below the waterline. This power primer etches into the aluminum, forming a strong surface/primer union that is resistant to corrosion. Choose the color that contrasts least with the topcoat you intend to apply over the primer.
For steel and iron surfaces, especially welded joints, above or below the waterline, use Zinc Cold Galvanizing or Zinc Phosphate. This corrosive barrier contains a high percentage (95%) of zinc, for maximum resistance against solvents & abrasions.
Available in a 12 oz aerosol spray can.
