PURPOSE: A painting method of an operation vehicle is provided to increase scratch resistance, weather resistance, corrosion resistance, and acid resistance. CONSTITUTION: A spraying method of a transportation unit includes as follows. A first step is to spray a painting composition including hardening organic resin, glass power, alkali material group composition or alkali earth metal system composition, metal powder, and solvent. A second step is to form a glass bead projection by hardening the glass bead by spraying the glass bead on upper side of a painting composition before hardening a sprayed painting composition. The painting composition includes a glass powder 10~400 parts by weight, a alkali metal group compound or a alkali earth metal system compound 0.1 - 10 parts by weight, metal powder 0.1 - 50 parts by weight, and solvent 100 - 500 parts by weight about hardening organic resin 100 parts by weight. The hardening glass resin is selected among one type from an epoxy group, an acryl group, a urethane group, an alkyd group, a polyester group, and a polyvinyl chloride group. The particle size of glass powder is 0.01~500 μm.
