Electrostatic dust removal; 7. Spray painting operation; 8. Apply gray primer; 9. Spray the pre-mixed color paint, followed by clear gloss paint, then polish after baking. A bumper consists of an outer panel, cushioning material, and crossbeam, serving the following purposes: 1. Provides safety protection; 2. Helps absorb external impacts; 3. Protects pedestrians; 4.

Let me share some DIY experience on painting a bumper. The usual process starts with removing the bumper to avoid overspray on other parts of the car. Then, sand the old paint and scratches with sandpaper to ensure a smooth surface. Cleaning is crucial—I use degreaser to scrub off dust and grease. Next, apply primer; this layer improves adhesion—spray one coat and let it dry completely. The color coat is key; use a spray gun to apply several thin, even layers, waiting a few minutes between coats to prevent runs. After that, spray a clear coat for protection against fading and scratches. Finally, place it in a drying booth or let it air-dry naturally for a day, then polish for extra shine. The whole process takes about 4-6 hours, and you'll need the right tools: spray gun, sandpaper, and masking materials. Remember, the environment should be dry and well-ventilated, or the paint may bubble or peel, ruining your effort.
