The irregular dent on the side of the fender is a small metal product, so the dent can be ejected from the inside. However, the sheet metal master who usually needs to dismantle the tire and lining will not choose to do so, but use a shaper to directly pull out the dent from the outside and level it. No matter which method is used in sheet metal forming, the antirust paint on the inside will be damaged. The painter will not spray the paint on the inside for you, but you can ask the maintenance personnel to spray the damaged paint on the inside again, and they will spray the paint on the inside according to your requirements. If you don't ask for the broken paint to be sprayed on the inside in advance, it won't be sprayed on the inside.
