Here are some tips for car painting: 1. Remove oil stains and rust from the car body surface, and degrease plastic surfaces to keep the car clean. 2. Use zinc-based phosphating solution to phosphorate 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, ensuring the paint is applied evenly and smoothly. 4. After painting, drive the car into a paint drying booth to bake and quickly solidify the paint. Car paint maintenance methods: 1. Wash the car only after the engine has cooled down. 2. Reduce exposure to direct sunlight. 3. Clean stains on the car body promptly. 4. Rinse with clean water after rain to avoid acid rain corrosion. 5. Apply wax or glaze.
I've learned quite a few car painting tips from experience. The first step—preparation—is absolutely crucial. You must thoroughly sand the car's surface, carefully removing old paint and rust with sandpaper, then clean with water and alcohol to eliminate grease and dust. This ensures the paint adheres properly. It's best to paint in a windless indoor environment with temperatures around 20°C and moderate humidity—too high, and bubbles may form or the paint may dry too quickly and crack. When using a spray gun, maintain a distance of about 20 cm, applying a thin, even coat. Wait 10 minutes before applying the second layer—never rush by spraying too thickly, or you'll get drips and bubbles. I often use newspaper and tape to protect glass and plastic parts from accidental overspray. Finally, allow at least 24 hours drying time before gently polishing to enhance shine. These are valuable DIY lessons—with practice, results can rival professional shops.
The trick to automotive painting lies in process control. The surface must be clean and smooth; I sand it with fine-grit sandpaper, rinse, and let it dry thoroughly to ensure no grease remains. Choose the right paint, such as water-based paint, which is more eco-friendly and dries faster. The ideal environment for spraying is 20-25°C with humidity below 50%, in a ventilated but dust-free area. Hold the spray gun 30 cm away, moving evenly with moderate pressure, applying thin coats and waiting a few minutes between each layer. Avoid thick coats to prevent runs; I test on a small area to ensure color consistency. After drying, wait patiently for 24 hours before polishing to avoid scratches. Don’t overlook safety—wear gloves and a mask to protect against chemicals. These small steps simplify repairs and keep the car body looking fresh and durable.
When I first started spray painting, I learned some practical tips. First, sand the car surface smooth and gently treat rust spots with sandpaper, then clean it thoroughly. Choose a suitable location for spraying, such as a wind-free area in the backyard or garage. Hold the spray can about 25 cm away and apply thin, even coats to avoid runs or peeling. Wait a few minutes between coats to let each layer dry. Wear old clothes to avoid getting paint on them. After spraying, let it ventilate and dry for a day. If there are imperfections, carefully fix them with fine sandpaper. Beginners should start with the bumper—it's cost-effective and great for practicing technique.
