A vehicle body composite coating, comprising, in succession, a polyurethane finishing coat, a polyurethane intermediate layer, a polyester putty and a micro-arc oxidation ceramic layer undercoat, wherein the micro-arc oxidation ceramic layer undercoat is on an aluminium substrate of the vehicle body. The design method of the vehicle body composite coating includes establishment of a physical model, selection of an optimal thickness ratio, preparation of the vehicle body composite coating and an erosion test. The vehicle body composite coating enhances the binding force between the whole coating system and the aluminium alloy substrate, reduces the possibility of shedding of the coating as a whole, and improves the anti-erosion performance of the vehicle body composite coating.
