A water-based metallic base coating composition suitable for forming a repair coating that does not give a sense of incongruity to an old metallic coating such as an existing metallic coating such as an automobile body. A multicomponent aqueous metallic base coating composition comprising a combination of a main component (I) and a diluent component (II), wherein the main component (I) is a urethane resin emulsion (A) and an acrylic resin. An emulsion (B), a glitter pigment (C) and water, and the diluent component (II) contains a viscosity modifier and water, the composition containing silica particles (D), and silica particles A multicomponent water-based metallic base coating composition characterized in that the average particle size of (D) is in the range of 0.1 to 25.0 μm, and repair coating using the composition Method.
