Does a 2 cm crack in the bumper need to be repaired? The specific introduction is as follows: Reasons for repair: The car bumper is a safety device that absorbs and mitigates external impacts, protecting the front and rear parts of the vehicle body. The owner can choose to repair or replace it based on the extent of the damage. If the damaged area is small, it can be repaired by welding. When the damaged area exceeds the standard for welding repair, a new bumper needs to be replaced. Methods for repairing the bumper: First, sandpaper and a grinder are needed to sand the damaged area, removing the paint around the damaged part. Clean with plastic cleaning fluid to remove surface dirt and impurities. Cut a stainless steel repair mesh that matches the size of the damaged area, fill it in the damaged part, and use putty to level the damaged area. After it dries, repaint it.
A while ago, I also had a crack about 2 cm long on my car's bumper. At first, I didn't take it seriously, thinking a small crack wouldn't affect driving. But later, I noticed that water would seep in during rain or car washes, and over time, the metal brackets inside could rust, especially where the bumper joints are prone to expanding cracks. Once on the highway, I even noticed slight deformation at the crack, which was quite concerning. My advice now is, even though you can drive for the time being, it's best to find time to get it professionally repaired. This prevents small issues from becoming big problems. The repair cost isn't high—just a few dozen bucks for regular plastic welding—safe and worry-free. Regularly checking for minor body damage is a lesson learned from driving.
