Some sealing strips are already installed on the car itself when it leaves the factory. The function of the sealing strip is to fill the gap between the parts of the car body, so as to achieve the functions of sound insulation, waterproof and shock absorption. However, some car owners choose to install some sealing strips in order to improve comfort, so what are the disadvantages of installing sealing strips on cars?

1, the automobile sealing strip is generally installed between the door and the bottom of the door, the front cover, the trunk and the B-pillar. Due to the addition of the sealing strip, it is very likely that the doors, trunk and other parts will not be closed normally, or even the sealing strip will be exposed after closing, which is very unsightly.

2. Installing the sealing strip can't improve the noise reduction a lot, because the sound insulation performance of the vehicle depends on many factors, and it is obviously unrealistic to just install the sealing strip.

3. The sealing strip belongs to rubber products and needs regular inspection and maintenance. If the sealing strip is aging, it is likely to fall off and affect the appearance.

Maintenance of automobile sealing strip;

1. Use car cleaner for cleaning. After cleaning, apply a highly permeable protective agent to prevent the rubber sealing strip from aging.

2. When the vehicle is driving at high speed, it is easy to cause the gap of the sealing strip to be filled with dust. Abnormal sound and corrosion will occur after a long time, so it is necessary to clean the dust with a brush regularly.

3. Check the door sealing strip for cracks. If there is, it can be repaired with adhesive. But if there are many and serious cracks, it is best to replace them.
