A coating device is provided to repair. When a spray gun (1)is at trip gear (34) and at pripping part side (8), a valve part (16) is apart from a valve seat part (15) and then start to open. The valve part (16) is mounted with an air restriction part (18) and properly decompresses the pressure even though the valve part (16) discharges bigger air pressure, thus the valve part (16) is very good for the painting dressing at half-on off state. In step of drying, a heating tube is set apart form the coating film of water system coatings at preset distance, the heating tube for emitting heat of preset wavelength field is subjected to heating of preset time and then at the state of keeping heating, the blower is used to blow in preset time. Even though the water system coatings of high viscosity are used, the thickness of painting dressing is gradually formed from the center to shading part. Without large equipment and high cost, the drying of coating film can be performed at high efficiency, even though the user is defective of experience, the painting dressing of high quality can be performed in short time.
