Summary:PROBLEM TO BE SOLVED: To search a method for forming a film of a water-based coating which is excellent in finish, chipping resistance, and water resistance in the line coating of automobile bodies. SOLUTION: The method comprises the steps of adjusting a water-based coating consisting essentially of a hydroxyl-containing resin (A) a blocked polyisocyanate compound and/or a melamine resin curing agent (B), and a flat pigment (C) so that (1) the solids content in coating may be 45 to 70 wt.%, and that (2) the coating viscosity at 20°C is 40 to 50 sec as measured with a Ford #4 cup and spraying the adjusted coating material over the substrate in a coating line under conditions including a spray booth temperature of 15 to 40°C and a spray booth humidity of 60 to 90%.
