What to Do When the Window Sealing Strip Ages?
2 Answers
When the window sealing strip ages, it needs to be replaced promptly. The window sealing strip is an accessory used to seal around the car door, improving airtightness and preventing wind and rain from entering the cabin. Once the door sealing strip ages and becomes damaged, it will increase the wind noise during driving, cause cabin leakage, and lead to rust on the car body. The door sealing strip is mainly made of ethylene propylene diene monomer (EPDM) rubber, which has good elasticity, resistance to compression deformation, aging, ozone, and chemical effects, as well as a wide range of operating temperatures. It is foamed and densely compounded, containing unique metal clamps and tongue-shaped buckles, making it sturdy, durable, and easy to install. The door sealing strip is mainly used on car doors, side windows, front and rear windshields, engine hoods, and trunk lids, serving functions such as waterproofing, dustproofing, sound insulation, temperature insulation, shock absorption, and decoration.
Window seal aging is a common issue that I've encountered before. Aging causes the seals to harden and crack, leading to windows not closing tightly, potential water leakage during rain, and increased noise. First, I check for any damage or gaps, clean the surface dirt with a clean cloth, and try applying some silicone lubricant, which can temporarily soften the seals. If the cracks are severe, don't hesitate—just replace the seals for reliability. DIY replacement isn't complicated: measure the dimensions, purchase a matching seal kit (available at auto parts stores or online for a few dozen bucks), gently pry off the old seal, and press the new one firmly into place. For daily maintenance, I make it a habit to wipe the window edges during each car wash to avoid prolonged sun exposure and premature aging. This approach saves money and ensures safer driving.
