PROBLEM TO BE SOLVED: To provide a repairing method of scratches on lens of vehicle lamp, especially scratches on polycarbonate lens, in which the scratches can be easily repaired while shrinkage is prevented, solvent cracking is prevented while high adhesion with base material is kept, and sufficient surface hardness can be obtained. SOLUTION: The repairing method includes a process in which the lens surface is polished to erase the trace of scratches and to remove an old coating on the lens surface, a process in which a primer containing silicone resin of 5-10 pts.wt., glycol solvent of 1-5 pts.wt., alcohol solvent of 16-35 pts.wt., aromatic hydrocarbon solvent of 1-5 pts.wt., ketone solvent of 10-20 pts.wt. and ester solvent of 10-20 pts.wt. is sprayed onto the area where the old coating was removed and then dried, a process in which a top coat material containing acrylic silicone resin as a coating-forming element is sprayed onto the area where the primer is applied and then dried, and a process in which the area where the top coat material is applied is polished.
