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.

Process for forming protective film on coated surface of automobile

In peeling off, from a coating surface, temporarily protecting coating films formed by applying a protecting coating material onto the coating surface after completion of the coating, high-pressure water is jetted toward between the coating surface and end edges of the temporarily protecting coating films to peel off the end edges from the coating surface. Then, the high-pressure water is jetted sequentially to between the coating surface and peeled-off portions of the temporarily protecting coating films from the coating surface to peel off the entire temporarily protecting coating films from the coating surface. Thus, the temporarily protecting coating films can be easily peeled off without being influenced by the temperature of an environment, leading to a shortened peeling-off time.
