Coating method for cationic electrodeposition coating material

A coating method for a cationic electrodeposition coating material, wherein a metallic article to be coated is coated by cationic electrodeposition, the method comprising:

• a step of immersing the metallic article to be coated in a first solution bath;
• a step of immersing the metallic article to be coated in a second solution bath;
• and
• a step of immersing the metallic article to be coated in a third solution bath,
• wherein at least one of the three steps includes a cationic electrodeposition coating in which a current is applied,
• wherein a coating film formed through the three steps contains at least a base resin component (A), a reaction component (B) and a catalyst (C), and
• wherein the first solution bath, the second solution bath and the third solution bath contain the base resin component (A), the reaction component (B) and the catalyst (C) in a combination of one or two of the components.
