The damage to a car bumper can be repaired, and the specific method depends on the extent of the damage. For minor scratches or dents, touch-up paint pens or hot water therapy can be used, leveraging the elasticity of the plastic material to restore it to its original shape. In case of cracks or breaks, a plastic welding gun with a special welding rod is required for welding, and a hole should be drilled at the end of the crack to prevent further expansion; if necessary, a stainless steel reinforcement mesh can be added to enhance structural strength. Modern bumpers are mostly composed of a plastic outer panel, cushioning material, and a metal beam, which serve to absorb impact and decorate the car body. During repair, attention should be paid to dust and oil removal to ensure the bonding effect, and putty and self-spray paint close to the original colour should be selected for appearance repair. If it is difficult to operate by oneself, It is best to seek professional repair services to ensure safety and quality.
