Is it just paint peeling off? Is the bumper deformed or damaged? Or touch the place where the paint has been removed with your hand, and feel whether the paint is consistent with the surroundings? If you don't need to do sheet metal, go to the 4S shop for painting. 4S will be required to make all bumpers, and the cost will exceed 1000 yuan. If you do it yourself in the paint shop outside, you can get it for 200 yuan
