PROBLEM TO BE SOLVED: To apply a vehicle coating agent evenly on a vehicle surface composed of coating, glass, rubber, plastic, etc., to give not only water repellency but also water slipping properties, and to make the vehicle coating agent uniformly act on the surface of the vehicle.SOLUTION: The present invention provides a vehicle coating agent composed of: trimethylsiloxysilicic acid (1); organopolysiloxane having a linear siloxane structure (2); nonionic surfactant (3); a cationic water-soluble high molecular compound having adhesiveness by cationic group (4); and water. Wash water is jetted on the surface of a vehicle after the vehicle coating agent is sprayed, and water washing is to be performed. Then the vehicle coating agent is applied once again. A jetting nozzle for spraying the vehicle coating agent is to be a full-conical nozzle with a substantially even flow rate distribution. |
