Auto Installation 101: Attaching a New Weatherstrip Seal
Are your car’s doors starting to leak or rattle? Then it’s time to strip off the old weatherstrip seal and install a new one. This often-forgotten component is responsible for providing an air-tight seal while the doors are closed. Once this part wears out, the doors might feel a bit loose, and air and water can easily get inside the cabin. So once you experience these signs, get your hands on a new seal and attach it as soon as possible. Here’s how:

Tools you’ll need:
Inspecting the replacement weatherstrip seal
Before you start with the actual installation, it’s best to take a closer look at the new seal. Make sure it’s the same as the old one. The new one should have the same thickness, shape, and holes as the old seal.
Removing the old seal
Using a screwdriver, you might need to remove screws in order to remove the worn-out seal. Once the screws are removed, gently peel off the old weatherstrip. For hard-to-remove bits, spray them with some weatherstripping remover first. Then once the weatherstrip softens, peel it off again and see if all the bits are removed. You can use the screwdriver to gently pry off any remaining strips. For leftover adhesives, spray them with some weatherstripping remover. Wait for the glue bits to soften up. Then remove them with a screwdriver.
Prepping the new seal
Once you’ve removed every bit of the old seal and glue, place the new seal onto the frame. Check if the new seal fits perfectly around the frame’s contour. Then remove it. Before attaching it, clean it with sandpaper or rinse it with water. This is to make sure that the new weatherstrip doesn’t contain any contaminants or rough spots.
Installing the new weatherstrip
Sparingly apply adhesive on the new weatherstrip’s back side. Then attach it onto the frame before the glue dries up. Make sure that the new seal snugly fits every nook and cranny of the frame. Then re-install any screws you’ve previously removed.
