ABSTRACT:
Metal treating compositions, formulated from precursor components, and containing chromic acid with pulverulent zinc and thereby finding particular utility in coating metal substrates prior to painting, can now have simplified precursor components. Such simplified precursor components may be easily and readily blended to form the metal treating composition. Yet such precursor components exhibit enhanced storage stability as well as compositional simplicity.
