As vehicles age, the rubber seals around the windows and doors can start to deteriorate, leading to air leaks, water intrusion, and excessive noise. Replacing these seals is a relatively simple task that can be done at home with a few tools and some basic knowledge. In this comprehensive guide, we’ll walk you through the steps to fix your car’s window seals and keep your vehicle in top condition.
Identifying the Problem
The first step in fixing your car’s window seals is to identify the problem. Look for the following signs of wear and tear:
- Loose or hanging seals
- Cracks or holes in the rubber
- Stiffness or lack of flexibility in the seal
- Excessive noise or air leaks
- Water intrusion into the cabin
If you notice any of these issues, it’s time to replace the seals.
Preparing the Surface
Before you can install new seals, you’ll need to prepare the surface. Start by removing the old rubber seal with a flathead screwdriver, gently easing it out and pulling it with your hands. If the rubber is too soft, it may break into pieces, so you may need to scrape it off in sections.
Once the old seal is removed, use WD-40 Multi-Purpose Product to remove any remaining adhesive or glue residue. Spray the lubricant onto the surface and use a rag to rub it in. Apply the lubricant again and rub vigorously until the metal is clean and free of any residue. Wipe off any remaining lubricant with paper towels.
Next, sand the metal surface with fine-grit sandpaper to create a smooth, even surface for the new adhesive. Sand in circular motions, being careful not to damage the surrounding paint. This step ensures that the new rubber seal will adhere properly and create a tight seal.
Applying the New Seal
Now it’s time to apply the new rubber seal. Start by cutting the seal to the appropriate length, allowing for a slight overlap at the ends. Dry fit the seal in the window to ensure a proper fit before applying any adhesive.
When you’re satisfied with the fit, apply a thin layer of weather stripping adhesive to the metal surface and a bead of adhesive to the inside of the rubber seal. Let the adhesive sit for 5-10 minutes to become slightly tacky.
Starting at one corner, gently press the new seal into place, working your way around the window. Apply firm pressure to ensure a tight bond between the rubber and the metal. Be careful not to stretch the seal as you apply it.
Once the seal is in place, press down firmly along the entire length to ensure a secure bond. Allow the adhesive to fully cure according to the manufacturer’s instructions, typically 24-48 hours.
Protecting the Seal
To extend the life of your new window seals, apply a layer of WD-40 Specialist Silicone Lubricant. This lubricant helps keep the rubber soft and flexible, preventing it from drying out and cracking over time. It also helps repel dust and moisture, keeping your seals in top condition.
To apply the lubricant, use the smart straw to reach into the corners and seams, ensuring even coverage. A single coat should provide long-lasting protection for your window seals.
With your new seals in place and protected, you can enjoy a quieter, more comfortable ride with reduced air and water intrusion. Regular maintenance, such as cleaning and lubricating the seals, can help extend their lifespan and keep your car in top condition for years to come.
