Can the bumper be partially painted?

Bumper paint can be partially sprayed, but compared to full spraying, there will be some color difference. The bumper is a safety device that absorbs and mitigates external impacts and protects the front and rear of the car body. It consists of an outer panel, cushioning material, and a crossbeam. The outer panel and cushioning material are made of plastic, while the crossbeam is formed by stamping a cold-rolled thin plate with a thickness of about 1.5 mm into a U-shaped groove. The outer panel and cushioning material are attached to the crossbeam, which is connected to the frame longitudinal beam with screws and can be disassembled at any time. The methods for repairing bumper scratches are: 1. Apply toothpaste to the shallow scratches and wipe with a soft cotton cloth in a counterclockwise direction; 2. Spray the car paint scratch repair agent onto the scratches and wipe with a towel; 3. Use a touch-up pen to spray and repair the damaged area along the direction of the scratch, and apply fine wax after it dries.
Last time I scraped the right corner of my bumper while reversing, and a friend recommended spot painting as a viable solution. In my case, the scratch wasn’t large—the technician masked off the area with special tape, sanded only the damaged section, and spent a long time matching the paint using the factory color chart before spraying. They even used a heat lamp to cure it. The key is color difference control—lighter cars show a more noticeable boundary after touch-ups, while black tends to blend more naturally. Small-area touch-ups can save half the cost, but if the car’s paint has faded over five years, the repair might look like a patch. If aesthetics matter, respraying the entire bumper might be the more hassle-free option.
