To small scratches and imperfections mend ideal. With reasonable care in preparing the defect of paint pen brings good results. Degrease flaw, carefully grind eg with brake cleaner eg 1000- 1500 wet sandpaper, then degrease again and interpret the defect / scratch / chipping in several layers. After about 4 days (Curing should comply) Can the repair be polished if required. I have used it so and got a perfect finish.
