The role of the car sealant should not be underestimated
If the car owner finds that the car window will leak water, it may be that the sealant is not waterproof. The sealing strip can play many functions such as waterproof, sealing, sound insulation, dustproof, etc. Therefore, you should also pay attention to it during maintenance. Also, remember to check the weatherstrip regularly for large cracks or breaks. After cleaning the sealing strip, you may wish to apply a layer of high-permeability protective agent, which can not only prevent the aging of the sealing strip, but also improve the sealing performance.
