Can a cracked rear bumper be repaired?
2 Answers
Yes, a cracked rear bumper can be repaired. The repair methods are: 1. It can be repaired using a plastic welding gun, which heats and melts the plastic welding rod and the surface of the film to achieve melting and bonding; 2. After repairing the crack, the area needs to be repainted and then dried; 3. For larger cracks, repair may not be possible. Even if it can be patched, it may be difficult to ensure its shock-absorbing function, so in such cases, it is necessary to replace the bumper with a new one. The car bumper is a safety device that absorbs and mitigates external impacts, protecting the front and rear of the vehicle body. It serves as a buffer when the car or the driver experiences impact forces.
My rear bumper also cracked last year when I accidentally scraped against a pillar while reversing. I drove to the auto repair shop near my neighborhood, and the mechanic checked it and said the small crack could be completely repaired without replacing the whole piece. He used a plastic welding gun to bond the crack, costing a total of 150 yuan and taking less than an hour. After the repair, it looked as good as new, and the strength was no issue. I recommend everyone not to delay—small cracks can expand over time, and windblown sand or rainwater seeping in can erode the internal structure. Regular body inspections can prevent such accidents, and leaving some space when parking is safer. Plastic bumper repairs are quite common, and choosing a reputable shop is crucial—don’t go for cheap, unlicensed workshops. Repairing saves money and is eco-friendly; replacing a new bumper also requires painting and color matching, which is more troublesome. After driving for so many years, addressing small issues early saves hassle and worry.
