Why is it recommended to replace bumpers during repairs nowadays?
2 Answers
Because the solution mainly depends on the extent of damage to the bumper. Here are some relevant introductions about bumpers: Function of the component: The car bumper (anti-collision beam), located in most areas at the front and rear of the car, is designed on the surface to avoid the impact of external damage on the vehicle's safety system. These have the ability to reduce injuries to drivers and passengers during high-speed collisions and are increasingly designed for pedestrian protection. Origin of the definition: The car bumper is a safety device that absorbs and mitigates external impacts, protecting the front and rear parts of the vehicle body. Twenty years ago, the front and rear bumpers of cars were mainly made of metal materials, pressed into U-shaped channel steel with steel plates thicker than 3 millimeters, surface-treated with chrome plating, riveted or welded to the longitudinal beams of the frame, with a relatively large gap from the body, as if it were an additional component.
I often help out at repair shops and see many cases of bumper damage. Why do most people now recommend replacement over repair? Plastic bumpers tend to crack or deform easily upon impact, making repairs particularly challenging. The process involves heating with a heat gun, sanding, filling, and repainting—not only time-consuming but also often resulting in imperfect outcomes like color mismatches or reappearing minor cracks. With new bumper prices dropping significantly and inventory being ample, replacement saves time and effort—done in just half an hour, ensuring both appearance and structural integrity. Safety is another concern; repaired bumpers may have reduced energy absorption in collisions, increasing risks. Insurance companies also prefer replacements to avoid future disputes. From practical experience, minor scratches can be repaired, but for major damage, opting for a new one saves money, hassle, and enhances safety.
