Spray paint cannot be used to repair car paint because using spray paint before applying normal automotive paint can cause reactions between the two, and it is difficult to control color differences, with poor adhesion. Below are specific details about car paint: Automotive Paint: Automotive paint is a protective film sprayed onto cars, a type of coating designed to make the car body less susceptible to corrosion. Minor Paint Damage: If wiping with a damp towel twice seems to remove it and the scratches are not very noticeable, simply applying wax is sufficient; use water-based wax or soft wax with abrasives, either in solid or liquid form. Advantages: Automotive paint has excellent performance, with good film fullness, high gloss, high hardness, and strong adhesion. The paint film has outstanding mechanical properties, excellent gloss retention, weather resistance, and abrasion resistance, as well as good resistance to acids, alkalis, alcohol, and gasoline. Spraying Method: Pearl silver metallic paint is applied in three layers. The first layer is a mist spray, with a faster gun movement speed, creating a thin, fog-like coating over the repair area or the entire car, allowing the paint to bond with the primer coat. The second layer covers the primer or putty red-gray layer, revealing the color, and care should be taken to avoid silver metallic paint streaks or unevenness, with a slightly faster gun movement speed. The third layer corrects any streaks or unevenness from the second layer. Overall, the goal is to achieve uniform color coverage over the repair area or the entire car.
