- move the heat source toward the coated surface to bake a wet coating film applied to the coated surface;
- and close the lid part after moving the heat source away from the coated surface.
A paint baking method for a vehicle body, the vehicle body having a main shell body to which a lid part is attached via a hinge, the vehicle body including a body exterior part and a coated surface of the main shell body and the lid part in a vicinity of the hinge, the paint baking method comprising:
- opening the lid part before moving a heat source toward the coated surface, the heat source giving heat energy primarily to the coated surface of the vehicle body being conveyed in a state of opening the lid part;
- moving the heat source toward the coated surface to bake a wet coating film applied to the coated surface;
- closing the lid part after moving the heat source away from the coated surface, thereby locally baking the coated surface;
- and
