摘要:
This invention is directed to a method for repairing coating defects on a coated substrate, such as autobody. The method includes mixing Part A and Part B of a coating composition to form a pot mix; applying an overlay of the pot mix over an affected area having the coating defect; partially drying the overlay; removing the excess of partially dried pot mix from the affected area by rubbing the affected area with a rubbing solvent mix wherein the rubbing solvent mix includes one or more hydrocarbon aliphatic solvents; and curing the partially dried overlay to produce a defect free area on the coated substrate. Part A of the coating composition includes one or more crosslinkable components and Part B of the coating composition includes one or more crosslinking components. If desired, the coating composition can include Part C containing pigments or dyes that match the color of the coated substrate.
