The bumper needs to be painted. The process of painting the bumper is as follows: 1. Clean the bumper thoroughly; 2. Dry the moisture; 3. Spray the surface; 4. Sand and wipe clean; 5. Flame treatment; 6. Electrostatic dust removal; 7. Spray painting operation; 8. Spray gray primer; 9. Spray the pre-mixed color paint, then apply clear gloss paint, and polish after baking. The functions of the bumper: 1. Safety protection; 2. Absorb external impacts; 3. Protect pedestrians; 4. Decorative purpose; 5. Improve the vehicle's aerodynamics. The bumper consists of an outer panel, cushioning material, and a crossbeam.
I've been in the auto repair industry for nearly 20 years and have handled countless bumper painting issues. Whether bumper painting is necessary mainly depends on the specific situation: For newly purchased unpainted bumpers, such as common plastic or metal ones, painting is generally required to match the car's body color, prevent rust, and enhance overall aesthetics. If an old bumper has severe scratches or exposes underlying material, painting can repair the damage and protect it; conversely, minor scratches can be left alone for the time being. In terms of cost, small-area painting can be done for a few hundred yuan, and money-saving methods include touch-up pens or DIY, but the results are not as good as those from professional shops. I'd like to remind everyone that rust prevention is crucial, especially in areas with heavy rainfall. A painted bumper lasts longer, and if left untreated, rust or discoloration over time can become more troublesome. I recommend first assessing the extent of the damage before deciding, as professional advice is very important.
