Is Adding Sealing Strips to Cars Useful?
2 Answers
Adding sealing strips to cars is useful. The main functions of car sealing strips are as follows: 1. Waterproofing: Primarily, they prevent external liquids and gases from entering the car, such as rainwater during rainy days, thus avoiding interference with the driver's normal operation. 2. Noise reduction: Additionally, while driving on the road, sealing strips can reduce wind noise and provide certain shock absorption, dustproofing, and decorative effects, simultaneously enhancing the driver's comfort and protecting the car body components. Precautions for replacing car sealing strips: 1. Before replacing the sealing strips, it is essential to select the appropriate style based on the ones used in your specific car model. Currently, there are many professional vehicle sealing shops in the market that customize sealing strips for different car models, ensuring precise matching with the original car's curve slope and curvature. This maintains continuity between various parts of the car body, avoids airflow separation at joints, easily resolves periodic wake flows, reduces wind noise at high speeds, and enhances the car's original airtightness and dustproof capability. 2. After selecting the sealing strips, remove the old ones before installation. Clean the areas to be covered by the new sealing strips thoroughly, especially residual glue, old dust, and sand. If possible, applying a layer of protective agent is recommended, as it can prevent the sealing strips from aging and significantly improve their sealing performance.
As an owner of an old car, I added door seals last year, and honestly, they really work. The main benefits are significantly reduced wind and road noise, especially when driving on highways. The whooshing wind sounds I used to hear are now much less noticeable, making the cabin much quieter. Listening to music or chatting is now much more comfortable. Additionally, the seals help keep out dust—after three years of use, the interior collects half as much dust, reducing cleaning frequency. They also prevent rainwater from seeping into door gaps. The downside is that installation requires care; if not applied tightly, they can let in drafts. I recommend butyl rubber seals for better durability. DIY installation costs just a few dozen bucks. Overall, the improvement in comfort is noticeable, especially for long-distance driving—definitely worth trying. Just be sure to choose a reputable brand and avoid the cheapest options.
