Take it to an auto repair shop for maintenance. The following are the methods for repairing a car's rear bumper: 1. Inspect the location and extent of the bumper crack damage. 2. Use a single-action sander equipped with 80-grit sandpaper to sand the paint surface at the cracked area. 3. Prepare a plastic welding gun to heat and weld the broken area. 4. Use the prepared PP welding rod with the plastic welding gun to weld along the crack. 5. Let it air dry naturally for several hours until the temperature returns to normal.
Last time, a small crack appeared on the rear bumper of my car. At first, I didn’t pay much attention to it, but later the crack expanded and water seeped in. I quickly went to a repair shop and spent 50 yuan to have it fixed with special adhesive. Handling small cracks yourself is quite simple—just buy automotive plastic tape or repair adhesive from Taobao, and the material cost is less than 30 yuan. However, if the crack is large, say over 10 centimeters, the bonding effect will be poor, and it’s recommended to replace the entire bumper, which costs a few hundred to over a thousand yuan. If not repaired in time, rainwater and dust can seep in, leading to rust on the undercarriage, which is unsafe in the long run. During regular car washes, pay extra attention to the corners of the bumper to avoid turning minor issues into major problems. Personally, I prefer DIY fixes for minor cracks, but for serious damage, don’t skimp—head to a professional repair shop promptly to ensure safe driving.
I've driven used cars for years and my biggest fear is ignoring a cracked bumper. The rear bumper isn't just decorative—it protects the car's rear structure. Once cracked, water and dust can easily enter, leading to body corrosion and rust. I've seen cases where delaying repairs for small cracks doubled the repair costs later. My advice: first clean the cracked area and use automotive reinforcement adhesive for a temporary fix to prevent worsening. Small issues can be DIY-repaired with tools costing just tens of yuan. For major cracks, visit a professional shop for thorough treatment—slightly more expensive but reliable. Don't just focus on surface aesthetics; the core issue is preventing safety hazards. Develop a habit of regular inspections—early detection and treatment save both money and hassle.
Don't panic if your car's rear bumper is cracked, prioritize simple solutions. I usually go to a quick repair shop for an assessment first. For small cracks, you can buy glue to fix it yourself for around 20 yuan; for larger cracks, let a professional technician handle it—it'll be done within half an hour, costing just a small amount for peace of mind. Delaying repairs can lead to rainwater seeping in and rusting the car's frame. While repairing, check for any other damage in the surrounding area to solve everything efficiently in one go. When driving daily, be careful not to hit hard objects while reversing to protect the bumper and avoid unnecessary trouble.
