Process for repairing coated substrate surfaces

A process for repairing coated substrate surfaces comprising the following successive steps:

• a) optionally preparing a blemished area to be repaired,
• b) providing a backing film coated on one side with only an uncured or at least partially cured coating layer of a coating composition curable by means of high energy radiation,
• c) applying the backing film with its coated side onto the blemished area to be repaired,
• d) irradiating the coating applied in this manner onto the blemished area to be repaired with high energy radiation and
• e) removing the backing film,
• wherein the coating is irradiated through the backing film and/or after removing the backing film and the remaining applied layer after removal of the backing film is the coating composition of step b).
