Vehicle painting steps are: 1. Remove oil stains and rust from the body surface, degrease plastic surfaces, and keep the car surface clean; 2. Use zinc-based phosphating solution to phosphating the body surface, then rinse with clean water, wait for the body to dry before painting; 3. Pay attention to air pressure and nozzle size during spraying, ensure the car paint surface is even and smooth; 4. After painting, drive the vehicle into a paint baking room to dry quickly and solidify the paint. Methods for car paint maintenance include: 1. Wash the car after the engine has cooled down; 2. Reduce exposure to direct sunlight; 3. Clean stains on the body promptly; 4. Rinse with clean water after rain to prevent acid rain corrosion; 5. Apply wax or glaze.
I've painted my car several times myself and have quite a bit of experience. The first step is to thoroughly clean the car body, using car wash foam to remove all grease and dust, ensuring the surface is spotless. Then sand the old paint surface, starting with coarse sandpaper to remove rust spots, followed by fine sandpaper for smoothing. Fill any dents with putty and let it dry thoroughly. Next, apply primer—I choose eco-friendly spray and apply two thin coats, letting each dry for over an hour. The topcoat stage is the most critical; generally, I spray three layers, maintaining an even distance with the spray gun to prevent bubbles or runs. Finally, apply a clear coat protective layer and polish it to a glossy shine. The entire process should be done in dry weather with good ventilation, and don’t rush—otherwise, the paint may crack. Practicing more can save money, but tool maintenance is key—clean the spray gun promptly after each use.
