The car painting process is: 1. Remove oil stains and rust from the car body surface, and degrease the surface of plastic products to keep the car surface clean; 2. Use zinc-based phosphating solution to phosphating the car body surface, then rinse with clean water, wait for the car body to dry before painting; 3. Pay attention to air pressure and nozzle size during spraying, and the car paint surface should be uniform and flat; 4. After the car paint is sprayed, drive the vehicle into the paint baking room for baking to make the paint solidify quickly. The maintenance methods of car paint are: 1. Wash the car after the engine has cooled down; 2. Reduce exposure to the sun; 3. Clean the stains on the car body in time; 4. Rinse with clean water after rain to avoid acid rain corrosion; 5. Wax or glaze the car.

I've done a lot of painting, and the whole process feels quite detail-oriented. First, you need to thoroughly clean the car body to remove dust and grease, preventing the paint layer from bubbling or peeling. Sanding the surface is a crucial step—using sandpaper to smooth out old paint and rust, ensuring the new paint adheres well. Next comes the primer, usually two or three layers of corrosion-resistant epoxy paint, which must dry completely before moving on. The next step is the basecoat, which is the color layer of the car body, with a wide variety of color options. Finally, the clearcoat is applied to protect the color layer and add gloss. The entire job is typically done in a paint booth to prevent dust contamination. In terms of tools, controlling the spray gun's air pressure and nozzle size is critical—otherwise, the finish will be uneven. Drying times vary, but an oven can speed things up. Paint quality affects both the vehicle's appearance and durability, and regular maintenance can keep the paint looking fresh for years, avoiding the hassle of repairs.

I've tried painting a few times myself and found DIY quite challenging but fun. First, clean the vehicle thoroughly—no slacking off, or else the paint will develop sand-like spots. Sanding requires a grinder or hand tools to ensure a flawless surface. After applying the primer, wait for it to dry and take a short break. When spraying the color coat, control the spray gun distance—too close and it'll be thick and run, too far and it'll be thin and fade. Next comes the clear coat; spray it smoothly and let it air-dry naturally. The tricky part is the environment—I did it in the garage, and dust getting mixed in meant redoing the work. The tool investment isn't small, with hundreds spent on spray guns and supplies, but it saves money on professional fees. After painting, the car looks brand new, boosting confidence. I recommend beginners practice on small parts first and take it step by step. The whole process can be done within three days—don't rush or cut corners.

I'm concerned about environmental issues during the painting process. Traditional methods use solvent-based paints, which release harmful substances and pollute the air. Nowadays, water-based paints are being promoted as a better alternative, as they emit fewer VOCs. The operation is conducted in enclosed spray booths with ventilation systems to minimize emissions. When cleaning tools, use recycling agents and dispose of waste safely. Surface preparation before painting saves resources, as repeated sanding is sufficient. Choosing low-carbon materials reduces environmental impact, and the durability of painted vehicles decreases the number of scrapped cars. Integrating environmental protection concepts into every step benefits both individuals and society.
