Methods to deal with rust spots on a car body: 1. Minor rust spots: If the rust spots are not very noticeable, simply apply wax; 2. Visible rust spots without damaging the paint: First clean the paint surface, then use a soft towel dipped in toothpaste to wipe back and forth, and finally wipe off with a clean towel; 3. Rust spots damaging the primer: After washing, use a touch-up pen (scratch repair pen) to cover the steel plate completely, let it dry, and then apply wax and polish; 4. Steel plate already rusting: Use fine sandpaper to sand the rusted area, remove the rust and smooth the scratches, then use a touch-up pen to cover the steel plate completely, let it dry, and finally apply wax and polish.
I often deal with rust spots on the car body myself. After driving for so many years, I've accumulated quite a bit of experience. When encountering rust spots, the first step is to thoroughly clean the affected area, using rust remover or sandpaper to completely grind away the rust layer—never be lazy and let it spread. If the rust is severe, you'll need to apply an anti-rust primer, let it dry, and then touch up with topcoat matching the original color. It's best to do this when there's less rain to avoid damaging the new paint. During regular car washes, frequently check the paint for scratches. Applying anti-rust paste to small wounds promptly can save a lot of money later. The job isn't difficult but requires attention to detail, and keeping the car body dry is most crucial.
