A method for repairing small surface imperfections on a vehicle body is provided that includes the application of an uncured layer to a thickness of up to 1.02 mm of a composition inclusive of a polyester resin, an acrylated urethane resin, a defoamer, and a particulate filler to the vehicle body or a cured putty thereon. The uncured layer is then exposed to actinic radiation to induce cure of the uncured layer to form a coating to fill the small surface imperfection on the vehicle body. A one component, UV-cured putty material for repairing small surface imperfections is also provides inclusive of a polyester resin, an acrylated urethane oligomer or polymer, a defoamer, a photoinitiator, and a particulate filler. The composition has an uncured viscosity of between 9,000 and 13,000 centiPoise.
