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.

Aging window seals are no small matter—they compromise sealing, causing excessive wind noise while driving and water leakage during heavy rain. I recommend first inspecting the seal condition: check for cracks or brittleness, and test its elasticity. If issues are found, clean surface grease with a damp cloth and apply rubber protectant to prolong its life. For severe aging, prompt replacement is essential. Replacing seals isn’t overly difficult: prepare replacement parts (preferably OEM for durability), basic tools like a screwdriver, remove the old seal carefully to avoid scratching the window frame, and test the seal after installation. From a professional standpoint, regular seal replacement saves hassle, while neglect leads to cumulative damage. Addressing it now is far more cost-effective than delaying.

Don't ignore aging window seals, they affect safety and comfort: Failed sealing can let wind and rain leak into the car, causing driving noise interference. My first step is to check the degree of aging by observing cracks and elasticity. Clean the seals, gently wipe away dust and corrosive substances, then apply specialized maintenance agents to slow down aging. For replacement, it's recommended to visit a repair shop—labor costs are affordable (around 100 yuan), offering both speed and reliability. For prevention, minimize prolonged sun exposure and contact with chemicals. Timely repairs ensure peace of mind on the road.

The rubber seals on my own car had aged, and previously, when it rained, water would drip inside, which was quite annoying. I went directly to the auto parts market to buy new rubber seals, opting for an economical material that cost less than fifty yuan. The process of replacing them: first, I pulled out the old seals, cleaned the bonding surface with alcohol, cut the new seals to the required length, aligned them carefully, and slowly pressed them into place. After finishing, I tested the window to see if it sealed properly. Here’s a little tip: in an emergency, tape can be a temporary fix, but for the long term, it’s better to replace them. If you’re on a tight budget, no problem—just choose the right material, and it’s a simple job to get done.
