A composition and method of synthesizing a composition from organic oils and industrial byproducts for use as a corrosion inhibitor coating is disclosed. The synthesis of a rapid setting ionomer is the result of iron-induced polymerization of oleic and linoleic acids, where an alkaline ionomeric reaction is facilitated with a small fraction of pure aluminum leaf at room temperature. At least one alkaline reagent is employed with at least one metallic additive to form metal complex ionomers that form a solid polymer. The resulting ionomer is stirred and applied on the substrate as a surface coating and it starts setting in less than thirty minutes.
