Painting should be performed under dust-free and well-ventilated conditions. The method is as follows: 1. Remove oil stains and rust from the car body surface, degrease plastic parts, and keep the surface clean; 2. Use zinc-based phosphating liquid to phosphorate the car body surface, then rinse with clean water, and wait for the car body to dry before painting; 3. Pay attention to air pressure and nozzle size during spraying, ensuring 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. Painting is a car repair technique that involves restoring the deformed parts of the car's metal shell to their original shape, then spraying special paint to make the deformed metal surface look the same as the undamaged parts.

There are actually many conditions to pay attention to when it comes to painting work. I prefer doing it at around 20°C—if it's too hot, the paint dries too quickly and can bubble, while if it's too cold, it takes forever to dry, wasting time. Humidity should ideally be kept between 50% and 70%. If the air is too damp, moisture can cling to the paint like fog, causing whitening or spotting. Ventilation is a must, but avoid using fans as they can stir up dust; instead, rely on a proper ventilation system or open doors and windows for natural airflow. The workspace should be clean and dust-free—preferably an indoor workshop swept thoroughly before painting. I always wear a professional mask and gloves to protect myself from inhaling harmful particles and to prevent solvents from irritating my skin. Surface preparation is also crucial: sand away old paint and rust, then clean thoroughly to ensure a smooth surface before spraying. Maintain an even spraying distance and movement speed, and set the spray gun to the right pressure for a consistent coat thickness. After painting, let it dry naturally in a dust-free, temperature-controlled environment for 24 hours—this ensures a beautiful, durable finish. Remember, if the weather is bad, don’t force it, or you’ll just end up with more rework hassle.

I learned a lot from my last experience painting an old car at home. The optimal conditions are warm weather between 15 to 25 degrees Celsius. Painting in hot weather causes the paint to dry too quickly, leading to cracks, while cold weather makes it dry like glue. Humidity should be controlled at around 60%, and avoid painting during the rainy season when humidity is high, as it can cause the paint to fog. Ventilation is crucial—don’t use a big fan as it will stir up dust; simply using door gaps for airflow is enough. Choose a clean garage, sweep the floor to reduce impurities, and I also laid down plastic sheets to protect the ground. Wear proper masks and goggles for safety. Practice steady movements with the spray gun—don’t rush. Sand the car body thoroughly to remove oil and rust before painting. After finishing, let the car sit undisturbed for at least a day to allow proper curing. Only by controlling the environment can you achieve satisfactory results. Painting isn’t easy—it’s all about accumulated experience.

When painting, my first consideration is safety conditions. Ventilation must be strong to allow paint fumes to dissipate promptly, reducing inhalation risks—otherwise, headaches and nausea may occur. A comfortable temperature between 15 to 25 degrees avoids overheating and heatstroke. Humidity should not exceed 70%, as moisture can exacerbate health issues. Keep the work area away from fire sources, as paint is flammable—no smoking nearby. Wear an N95 mask, long sleeves, and gloves for full-body protection. With proper environmental control, your body stays safe, ensuring pleasant and efficient work.
