How to Repair Damaged Rubber Around My Car Window

Updated February 21, 2017

Rubber trim is commonly used around car doors and windows to help prevent outside elements, such as rain, from getting into the vehicle. Over time, this trim can become damaged and begin to peel off. Repairing the rubber trim is essential to keep any car in good working order and is a task that can be completed by any car owner with just a little bit of patience.

Open the door of the car where the rubber trim is damaged. Find the spot where it is damaged and stick a screwdriver into that spot. Gently, so the car does not get scratched, push down under the trim and begin prying it off. Pry until enough of it is free so that it can be peeled off. If the trim breaks off, begin again with a screwdriver.

Wash the area where the trim was located with Goo Gone to remove any leftover residue. Scrub it with a rag and allow proper time to air dry. Wash the area once again with automotive cleaner and water to remove any remaining residue. Dry off with a rag.

Sand down the freshly cleaned area with sandpaper to smooth out the surface. Sand in slow, circular motions until the entire area has been covered, and brush off the debris from the sandpaper with a paper towel.

Apply weather stripping adhesive to the area where the rubber trim will go and then apply a coat to the new trim. Allow the adhesive 10 minutes to adhere to the car. Set the new rubber trim exactly in the same spot where the old one was located. Hold it tightly in place for a few minutes.


It is better to use a flat head screwdriver than a Phillips head because the flat tip fits neatly beneath the rubber trim. For a better seal, it is common to place masking tape over the new rubber trim once it has been placed on the car. Remove the masking tape after a few hours.
