PROBLEM TO BE SOLVED: To realize uniform thermal conduction to a coating film in a thermosetting treatment stage and to prevent the generation of a boiling phenomenon by interposing a water removing stage for removing water on a surface of an automotive body between a washing stage and the thermosetting treatment stage. SOLUTION: A water removing stage for removing water 5 on a surface of an automotive body 1 is interposed between a washing stage and a thermosetting treatment stage. Thereby, the water 5 left on or adhered to a half-baked coating film 3 and an electrodeposition coating film 4 by washing in the washing stage is removed. Therefore, obstruction of thermal conduction by a water drop or water pool is not generated in the thermosetting treatment stage and uniform thermosetting treatment of the half-baked coating film 3 and the electrodeposition coating film 4 can be attained. Generation of the boiling phenomenon of the water 5 is prevented and generation of trace of the water, trace of the water drop, a water mark, and the like, can be prevented. Furthermore, in the water removing stage, the water 5 can be removed effectively in a short time because the water 5 is removed by air-blowing from a nozzle 6 which blows air onto a limited part where the water 5 is adhered.
