Abstract
Composite-coated flat-rolled sheet metal substrate subject to surface oxidation, after surface cleaning and oxidation removal is cathodically E-coated with minimal organic coating to stabilize such surface to prevent oxidation prior to application of protective organic coating finish to provide a total coating weight on each surface selected in the range of about 3 to about 20 mg/in.sup.2 of organic coating per surface. Such E-coat being applied to such substrate after removal of surface oxidation so as to enhance coating adhesion of end product protective organic coating. Lubricant for draw processing is embodied in the protective organic coating as a 'blooming compound' or can be precoated after such organic coating to enable draw-processing of articles such as a unitary cup-shaped can body while maintaining desired full surface protective organic coating to meet requirements for such article.
