Vehicle body coating method for automobile

A vehicle body coating method for an automobile, comprising:

• a step of press-forming a precoat metal sheet in which a rust-preventing layer and a coat which contains a lubricating component and aims to improve the finish (appearance and durability) of overcoating are formed in that order on at least an outside surface of a metal sheet, thereby producing plural exterior members, such as a bonnet, a trunk lid, doors and fenders, which constitute an outside of a vehicle body;
• a step of press-forming a precoat metal sheet in which a rust-preventing layer which contains a lubricating component is formed on a surface of a metal sheet, thereby producing plural inside members, such as a floor panel and an inner panel, which constitute an inside of the vehicle body, and joining the inside members to produce a chassis for the automobile;
• a step of joining the exterior members to the chassis;
• and
• a step of performing overcoating on surfaces of the exterior members joined to the chassis.

• a step of forming plural chassis constituent members from sheet materials, profiles or castings, each made of an aluminum alloy, and joining the chassis constituent members to produce a chassis for the automobile;
• a step of joining the exterior members to the chassis;
• and
• a step of performing intermediate coating and overcoating on surfaces of the exterior members joined to the chassis.
