Installing sealing strips on a car is useful. Automotive sealing strips serve to fill various gaps between body components, providing functions such as vibration reduction, waterproofing, dustproofing, sound insulation, and decoration. They enhance the comfort of the driving experience and protect the vehicle body. They are primarily applied to the door panels, door frames, front and rear windshields, engine hood, and trunk lid. The method for installing automotive sealing strips is as follows: 1. Thoroughly clean and dry the areas where the soundproof sealing strips are to be installed and the flat surfaces of the sealing strips; 2. Select the appropriate adhesion position, locate the starting point for adhesion, and begin pressing and adhering the sealing strips from the starting end; 3. After ensuring that all strips are properly adhered and checked, make appropriate adjustments to the soundproof strips, then press them down carefully by hand.
I used to drive an old car and decided to try installing sealing strips. After installation, the effect was noticeable—wind noise on the highway was significantly reduced, and the sound of closing the doors became much more solid. It also helps prevent rainwater from seeping in, especially during the rainy season in the south, keeping the interior cleaner and improving AC efficiency for a cooler summer. However, it’s important to choose a reliable brand, as low-quality strips may crack and fail within months. Installation is simple: just clean the door edges and press them firmly in place—a DIY job that takes less than an hour. The cost is just a few dozen yuan, much cheaper than buying a new car. Overall, driving comfort improves significantly, but don’t expect it to solve all problems—aged sealing strips may loosen and cause even more noise. I recommend regular inspection and maintenance for older cars or those who prioritize daily quietness.
