The methods for painting a car are: 1. Remove oil stains and rust from the car body surface, degrease plastic surfaces, and keep the car surface clean; 2. Use a zinc-based phosphating solution to phosphorate the car body surface, rinse with clean water, wait for the car body to dry, and then proceed with painting; 3. Pay attention to air pressure and nozzle size during spraying, ensuring the car's paint surface is even and smooth; 4. After painting, drive the car into a paint drying room to bake and quickly solidify the paint.
I was really worried when I saw rust holes on my car last time. First, you need to clean the area thoroughly and sand off all the rust with sandpaper to expose the metal surface. If there are significant holes, you'll need to patch them up with some sheet metal or welding material to prevent leaks or further deterioration. Applying a rust-proof primer is crucial. Once it's dry, apply body filler, sand it smooth, and finally spray on the topcoat to match the color. You can handle it yourself with sandpaper and spray paint cans, but for larger holes, it's recommended to go to a professional shop where they have the equipment to weld and patch more securely. For prevention, don't skimp on car washes, especially after rain, and spraying some rust-proof spray on the undercarriage can help avoid recurrence.
To deal with rust holes, I use a simple and cost-effective method. First, clean the rusted area and dry it with a cloth. Then, use coarse sandpaper to slowly grind away the rust. For small holes, find some metal patches or fillers to stuff in and press tightly. After that, spray a layer of rust-proof paint and wait for it to dry, then cover it with matching automotive spray paint, applying multiple coats for good coverage. The tools can be bought for just a few dollars at a hardware store, saving you from spending a fortune on repairs. Park your car in dry places regularly, and after washing, apply some lubricant to rust-prone areas as a preventive measure. This easily extends your car's lifespan.
