Can Rusty Paint Scratches Be Repaired?

[VonKyle]

For rusty areas on car paint, you can first use a wire brush or sandpaper to remove the rust, then proceed with spray painting or touch-up. Below is relevant information about paint cracking: 1. Explanation: If corrosive substances such as bird droppings or tree sap adhere to the car body and are not cleaned for a long time, exposure to high summer temperatures can cause the paint to crack. 2. Precautions: During car usage, it's important to maintain the car paint. Avoid washing the vehicle under direct sunlight to prevent paint cracks due to sudden temperature changes. Regularly inspect the paint surface; if cracks or impact damage are found, address them promptly to prevent further deterioration from wind and sun exposure. For minor scratches or chips, common solutions include sanding the surface with water sandpaper and applying touch-up paint with a detailing pen or using the auxiliary paint provided by the manufacturer. If these are unavailable, evenly applying white toothpaste can also be effective, especially for white car paint. Avoid using car covers for heat protection, as they can cause friction between the paint surface and the cover's interior, especially in breezy conditions, which may inadvertently wear down the paint surface.
