Not repainting the rear bumper will not cause the damage to spread. Rear bumper repainting procedure: For more severe scratches where the underlying primer color is visible, the decision to repaint depends on the location of the damage. Typically, bumpers, side mirrors, and some wheel arch parts are made of engineering plastic that won't rust, so repainting is optional based on owner preference. Before use, shake the touch-up paint pen thoroughly, then carefully apply along the scratch direction. After the touch-up area dries, apply fine wax. If the front bumper has collision-induced dents without paint peeling or chipping, visit a 4S shop for repair - each dent repair takes approximately 20-40 minutes. Bumper maintenance methods: Use a pressure washer and silicone remover to eliminate dust and stains from the vehicle body.
