Process for forming protective film on coated surface of automobile

Abstract

A strippable paint is poured down onto coated surfaces,and,of an automobile V within regions to be protected, from a plurality of nozzles,disposed in parallel in a widthwise direction of the automobile V above the coated surfaces,and,of the automobile V, while controlling the number of nozzles which are used to discharge the strippable paint, in accordance with the extent of the regions to be protected. Thereafter, the strippable paint is spread over an entirety of the coated surfaces,and,in the regions to be protected. Thus, the region covered by each of the nozzles can be relatively reduced to efficiently carry out the pouring-down of the strippable paint and to prevent dusts of a coating material from being scattered to a wide range. In addition, the need for a masking step and/or an inspecting/correcting step can be eliminated to reduce the operating steps and further to alleviate the operational load.
