Methods for dealing with scratches on the plastic bumper of a car: 1. Treatment for minor scratches: For more severe scratches where the underlying primer color is visible, the treatment depends on the location of the damage. Generally, bumpers, side mirrors, and some wheel arches are made of engineering plastic and will not rust. 2. Treatment for scratches that expose the primer: Touch-up pens are available at most automotive stores. The owner can provide the car model and official color name to purchase a touch-up pen with the correct color code. Before use, shake the paint inside the touch-up pen well, then carefully apply it along the direction of the scratch. Once the applied area is dry, polish it with fine wax.
I had similar scratches on my car door last time and fixed them myself. First, thoroughly clean the scratched area to remove any dust. Purchase a touch-up pen with the same color code and a plastic repair compound. For deep scratches, use the repair compound to fill them in evenly, wait until it's completely dry, then lightly sand it smooth. Apply the touch-up paint in thin layers multiple times, with a ten-minute interval between each layer. Finally, use fine wax to polish the edges and eliminate color differences. Perform the entire process in a shaded area, as direct sunlight can cause bubbles in the paint. Although it's not as good as professional spray painting, the scratches are barely noticeable from five meters away, and the cost is only a few dozen yuan. After the repair, it's recommended to regularly wax the paint surface to prolong the repair's lifespan.
