The most worry free and effortless way is to go to a 4S store or repair shop to find a technician to replace it, and of course, the cost will also be higher. If you have good hands-on ability, you can choose the corresponding model online based on your own car model, buy it yourself, and replace it yourself. However, it should be noted that while removing residual glue, dust, and sand, it is best to apply a layer of protective agent to delay the aging of the sealing strip and improve its sealing performance.
Also, be careful not to block the water outlets at the car doors, skylights, etc. Due to the thermal expansion and contraction characteristics of rubber, the length of the sealing strip should be longer than the assembly edge of the door and window during installation, leaving sufficient expansion and contraction allowance.
