Over time, the rubber seals around your windows and doors can begin to deteriorate. Cracks can appear, and joints can unravel leading to further damage. This can allow water, dust and car emissions into your car interior, making the cleaning process more bothersome.
If you’re noticing these signs, its time to do some maintenance asap! Follow this handy guide to find out how to fix rubber seals on your car.
How To Remove The Damaged Rubber Seal From Car
To begin with, open all windows and doors in your car, so you have as much space as possible to manoeuvre around your rubber seals. Using a flat head screwdriver, gently work your way around the rim of the seal you are working on to detach it. Once you have removed a small part, you can continue to pull it away with your hands. Take caution if the rubber begins to crack, as this can make it more difficult to remove.
Remove the glue residue from the car rubber seal
Now that you have removed the rubber, you need to remove any remaining glue residue. To do this, grab a bottle of WD-40® Multi-Use Product and shake it well. Spray the product over all of the affected area and allow it to penetrate the glue. After a few minutes, use a clean microfiber cloth to vigorously wipe the surface until no residue remains. For stubborn areas, reapply WD-40® product and repeat the steps until you are happier with the result.
When you are happy with the result, finish with a wipe using a clean paper towel to ensure no product remains.
Sand the metal surface of the car
Now that your surface is clean and glue free, we recommend lightly sanding the area before reapplying a new seal. Using a fine grit, gently sand the metal area where the seal will go, taking care to avoid damaging any paintwork. This will allow any remaining residue from the previous steps, too.
Apply glue for the new door or window joint
Once your surface is clean and smooth, you have the perfect surface to place the glue down for your new seal. Before you add the glue, make sure that your new rubber seal fits the gap, or trim it accordingly.
Use the rim of the seal as a guide and apply your glue to the clean surface. You can also add a few dabs of glue to the seal itself, to make it extra secure.
How To Install Car Door Rubber Seals
After applying the glue, allow it to set for a few seconds before applying the seal. Line up the seal and begin pressing it down firmly beginning in one corner and moving your way down to the opposite corner. Take care to ensure you don’t stretch the rubber, as this can lead to cracking further down the line.
Once you are happy with the alignment, press the entire seal again to fix it permanently. Avoid closing the door or window until the glue is fully dried and settled.
How To Protect Rubber Seals on Cars
To elongate the life of the seal, you can take steps to protect the rubber. WD-40® High Performance Silicone Lubricant is ideal for use on rubber materials. After you have allowed time for the glue to dry and settle, spray the entire rubber surface with WD-40® High Performance Silicone Lubricant, and wipe away with a clean microfiber cloth.
This step will protect the rubber from cracking and other damages caused by lack of moisture. You can repeat this action as many times as needed, and throughout the year when the weather conditions may cause further problems.
