Anodic electrophoretic coating method

A method for anodic electro-dip lacquer coating, wherein coating medium which is consumed in an anodic electro-dip bath is compensated for by an under-neutralized anodic replenishment material, where in the replenishment material comprises:

• A) a pigment-free aqueous binder vehicle component with a solid content of 40 to 70% by weight, based on the weight of the vehicle component, an MEQ value of 15 to 40 and a content of organic solvent of 0.5% by weight based on the weight of the vehicle component, and
• B) a pigment-containing aqueous paste resin component with a solid content of 60 of 75% by weight, based on the weight of the resin component, an MEQ value of 5 to 15 and a content of organic solvent of 1.0% by weight, based on the weight of the resin component,
• wherein A) and B) are present in a ratio by weight of 1:1 to 4:1 and the mixture of A) and B) has a solid content of 45 to 73% by weight based on the weight of the mixture of A) and B), and an MEQ value which is 50 to 70% lower than the MEQ value of the electro-dip bath.
