What are the methods for repairing plastic car bumpers?

[ElianaRose]

Repairs are categorized into minor scratches and larger scratches. The specific details are as follows: Minor scratches: For more severe scrapes where the underlying primer color is visible, the repair depends on the location of the damage. Typically, bumpers, side mirrors, and some wheel arches are made of engineering plastic, which does not rust. Whether to repaint depends on the owner's preference. Scratches exposing the primer: Touch-up pens are available at most auto parts stores. The owner can provide the car model and official color name to purchase the correct color-matched touch-up pen. Dented scratches: If the front bumper has dents or scratches from a collision without paint chipping or peeling, it should be repaired at a 4S shop. A dent repair typically takes about 20–40 minutes. Most 4S shops have specialized dent repair tools, such as suction cup handles, electric heaters, and small pry bars. After the dent is repaired, the scratches can be treated as needed.
