Methods for removing rust spots from a car are as follows: 1. Use a grinder to sand the rust, ensuring the surface is as smooth as possible and the rust is completely removed. If any residual rust remains, continue sanding until the surface is smooth and rust-free. 2. Take a clean piece of cardboard, add body filler and hardener, and mix them thoroughly until fully integrated. 3. Apply the well-mixed body filler and hardener compound onto the rusted area. Check for any spots that may not have been adequately filled and apply more of the mixture, then wait for it to dry. 4. Once dry, use a polisher to polish the area.
I often encounter rust spots on my car, and dealing with them is actually quite simple. First, gently sand the rusted area with sandpaper or a wire brush to remove surface rust, being careful not to apply too much pressure to avoid scratching the good paint. Then apply a rust remover; products like WD-40 are very practical as they penetrate and prevent rust from recurring. After it dries, apply a layer of rust-proof primer and topcoat, matching the car's color. The whole process can be done at home, and the tools can be bought at auto parts stores. The key is to wash and clean the car before starting to avoid dust interference. Finally, remember to regularly check the paint surface. If rust spots reappear frequently, it might indicate exposed edges or the undercarriage, and applying some undercarriage rust-proof coating can prevent major repairs.
