Is it useful to apply sealing strips to a car?

Applying sealing strips to a car is useful. Sealing strips can serve functions such as windproofing, leak prevention, and vibration reduction, reducing noise during car operation. There are various types of sealing strips, including water cut, door frame, door opening, engine hood, trunk, sunroof, front and rear windshields, as well as some decorative strips. More information about car sealing strips is as follows: 1. Installing car sealing strips can relatively improve the sound insulation effect of the car, and the sound of closing the door will appear more solid. 2. It will enhance the sealing effect of the car. Whether in summer or winter, air conditioning is used when driving the car. Therefore, only by installing car sealing strips can the sealing effect be better, and in summer, there is no need to worry about the cold air escaping.

Last month, I added sealing strips to my car, and honestly, the improvement was quite noticeable. The most direct benefit was the reduction in wind noise, especially when driving at 120 km/h—my ears didn't feel as uncomfortable. The strips were inserted into the gaps between the doors and the car body, and I could clearly feel that the door-closing sound became more solid. I also noticed that the air conditioning worked better; the cold air didn't dissipate as quickly from areas that used to leak. However, the strips do need to be replaced periodically as they age. The rubber ones I bought started to deform at the edges after about six months. For car owners who already have noticeable gaps in their doors or frequently drive on highways, adding sealing strips is definitely worth it.

Adding sealing strips to old cars is indeed useful, but it depends on the situation. My ten-year-old car had particularly large gaps around all four doors, creaking over speed bumps. After installation, the most noticeable improvement was less dust—previously, I had to wipe the dashboard daily, but now it's only every two or three days. The need to slam the doors shut hasn't changed, but there's no more water leakage during rain. For new cars, adding these strips doesn't offer much improvement since the factory sealing is sufficient. However, don't buy the cheapest strips—they can harden and crack under prolonged sun exposure. My colleague bought low-quality ones that started peeling off in just three months.

Just added door seals and here's my experience. The biggest surprise is the improved sound quality, especially the bass which feels more solid. It's probably due to reduced resonance from proper sealing. It also helps block out exhaust fumes if you rarely open the windows. However, they can get sticky on the window frames after summer sun exposure, so regular rubber protectant spray is needed. Cost about 200 yuan and can be DIY installed, but complex areas like A-pillars are better left to professionals. Worth trying for those with high noise insulation requirements.

Sealing strips are like a timely aid for old cars. After five years of driving, I could fit my little finger into the door gaps of my car. After adding D-shaped strips: 1. The high-speed wind whistle disappeared. 2. The warm air in winter became more concentrated. 3. No more water seepage during car washes. But be careful to avoid the drainage holes—I initially misapplied them, causing water accumulation. I recommend choosing 3M material with adhesive backing; mine has stayed firmly in place for eight months now. Highly recommended for vehicles frequently driven on construction sites—the dustproof effect is remarkable.
