Abstract
In repairing by electrodeposition coating an end or top plate of an easy-open can along a score groove where the material metal has been exposed or along a deteriorated coated film chiefly on the reverse side of said end, a sine wave A. C. voltage is imparted as the bath voltage under the particular conditions, wherein the electric current of reverse direction is effectively utilized to effect penetration of the deteriorated coated part or removal of wax. In this case, special advantage can be obtained if an electrode made of the particular metal having an anodic oxidation film thereon is used.
