Trunk Weatherstripping

Old, cracked and flattened trunk weatherstrip can be a real eyesore as well as a source of leaks. Also, old rotting rubber can become porous, holding rust-causing moisture in the groove around your trunk. New trunk weatherstrip is easy to install yourself.

1) There are two ways to remove your old trunk weatherstrip: first, use a heat gun or blow dryer on the underside of the trunk groove to loosen the old glue. We recommend performing this step before painting your car. If your car is already painted, be careful not to apply too much heat and discolor your paint.

1a)Second, and best, is to use 3 M Release Agent. Start at the seam and apply liberal amounts of release agent as you pull up on the old weatherstrip. Continue until weatherstrip is completely removed. You can use the release agent to remove any glue residue without harming your painted surfaces.

2) Next, use a scraper to remove any stubborn chunks of rubber or glue. Be sure to clean any dirt, rust or debris out of the groove. Now is the time to paint your car if applicable.

3) To install new weatherstripping, start by running a small amount of weatherstrip adhesive inside the groove. Do a little at a time.

» Hint: cut a small piece of old squeegee to fit the groove and use it to apply the adhesive.

» Note: For clipped trunk seals refer to door weatherstrips, item 6A.

4) At the center of the rear of the trunk, near the lock cylinder, begin inserting the new weatherstrip making certain both locking edges are fully installed and that the sealing edge faces outward from the interior of the trunk. (Figure 1) Looks like an ocean wave at top of weatherstrip.

5) Start the glue about 8" after the center and continue gluing to about 8" before center. Cut the end squarely, allowing ¼" extra for a tight bond. Apply adhesive to the trunk channel, and a small amount to the ends. Hold the ends together for a moment, and then insert the weatherstrip into the groove. The job is complete.

6) Check the alignment of your trunk lid. SoffSeal weatherstripping is designed to fit factory gaps.

» Note: Do not overlook your body seams as a source of leaks. SoffSeal’s weatherstripping is the correct height and tolerance as the original. Do not use your old flattened weatherstripping as a gauge for fit.
