To provide a method for repairing a coated surface of a vehicle, using an ultraviolet curing resin having excellent quick-drying property, and giving a good finish in a shortened working time, a method for repairing the damage on a coated surface of a vehicle being a depression and/or a depletion of a coating film, which is characterized by comprising the following steps a) to c): a) filling a putty raw material comprising an ultraviolet polymerizing resin composition in an optionally pretreated damage portion and ultraviolet curing the putty raw material to fill the damaged portion with the putty; b) uniformly spray coating, on the coated surface including at least the putty-covered surface after the step a), a primer surfacer raw material comprising an ultraviolet polymerizing resin composition having a viscosity sufficient for spray coating and ultraviolet curing the obtained raw material coating film to form a primer surfacer layer; and c) applying a top coat on the primer surfacer layer obtained in b).
