PROBLEM TO BE SOLVED: To provide an aqueous air-dry type coating for overcoating which is used in cases including an undercoat layer of an oxidation polymerization type coating.SOLUTION: An aqueous air-dry type coating composition is used in a coating method which includes applying an oxidation polymerization type coating in undercoating and applying an aqueous air-dry type coating in overcoating. The aqueous air-dry type coating for overcoating contains a film formation resin other than the oxidation polymerization type and a metal drier, and the blend ratio of the metal drier is 0.01-3.0 mass%, based on the metal content, relative to the solid content of the resin. |
