Provided is a method of coating a strippable coating material capable of achieving uniform adhesion between a painted surface and a strippable coating composed of the strippable coating material. The method of coating the strippable coating material includes steps of: typical vehicle coating to form an electrodeposition layer, an intermediate coating layer, a base layer, and a clear layer on a coated object; polishing the painted surface of the coated object using an abrasive so as to form uniform irregularities on the painted surface; degreasing to perform a degreasing treatment on the polished painted surface; and coating the strippable coating material on the polished painted surface.

Method of coating strippable coating material

An information processing device includes a processor configured to provide an incentive to a first user who sells or returns a first vehicle in which a part of a first coating film including an easily peelable layer is not peeled off.
