Product Description
Prime and protect bare aluminum with AlumaProtect two-part epoxy.
Waterproof AlumaProtect 4400/4401 is a two-part strontium chromate primer designed to form the ideal barrier coat over roughed bare aluminum. This is the appropriate epoxy to use when aluminum has been sandblasted, sanded or ground so that a “tooth” is present.
AlumaProtect provides maximum resistance to fresh- or saltwater, thus eliminating corrosion. This complete coating system resists water, industrial chemical fumes, and very humid environments. Intended to be used as a primary coat over bare aluminum hulls and outdrives.
AlumaProtect 4400/4401 will chalk if not topcoated. For sandblasted aluminum hulls, two coats of AlumaProtect are recommended. Then overcoat with Pettit Protect 4700/4701 for optimum results before finishing with antifouling paint. Use AlumaProtect for maximum corrosion control.
