The function of automobile sealing strip is to fill the gap between the components of the car body, and has the functions of sound insulation, shock absorption, water and dust prevention. It can not only improve the comfort of driving experience, but also protect the car body. However, in the face of severe cold and heat, wind and rain for a long time, it will naturally age and damage over time. If obvious cracks are found on the sealing strip, it must be replaced in time.

After the aging of the sealing strip, the sound of closing the door is not so "gentle", the noise of the car is getting louder and louder, the refrigeration effect of the air conditioner is getting worse and worse, and even water seepage and rain leakage may be caused by the aging of the sealing strip.
