The Rear Door Weatherstrip Seal set (Left & Right) DWP 3120 05 restores proper rear door sealing to keep water, dust and wind noise out of the cabin. Made for direct-replacement applications, these seals provide long-lasting flexibility and weather resistance to help prevent interior water damage and reduce drafts. They’re ideal for restoration projects and routine maintenance — verify fitment for your specific year/make/model before purchase — and are designed for straightforward installation to return doors to factory-like sealing performance.
Features:
- Includes left and right rear door weatherstrip seals — part number DWP 3120 05.
- Premium weather-resistant EPDM-style rubber maintains flexibility in hot and cold conditions.
- Restores watertight sealing to prevent leaks, reduce wind noise, and protect interior trim.
- Direct-fit profile follows factory door channel contours for easier installation.
- Ideal for vehicle restoration, routine maintenance, and replacing brittle or torn seals.
Installation / Application:
- Difficulty: 2/5
- Estimated time: 30–90 minutes (both doors, depending on adhesive use and vehicle)
Instructions:
- Prepare the workspace: park on level ground, open the rear door fully and support it if needed.
- Remove the old seal: gently pry the weatherstrip out of the door channel with a plastic trim tool; remove any retaining clips or fasteners.
- Clean the channel: remove old adhesive and debris with adhesive remover, then wipe clean with rubbing alcohol and a microfiber cloth. Allow to dry.
- Test-fit the new seal: align the new left/right seals along the door edge and confirm length and orientation. Trim excess if necessary.
- Apply adhesive (if required): follow the adhesive manufacturer’s instructions — apply a thin, even bead to the channel or to the weatherstrip contact surface.
- Install the seal: press the weatherstrip firmly into the channel starting at one end and working around corners; ensure the sealing bead seats fully and any retaining lip engages.
- Secure while curing: use masking tape or small clamps to hold the seal in place if adhesive was used. Wipe away any squeeze-out adhesive immediately.
- Reassemble and check: reinstall any removed trim or clips, close the door and inspect for gaps. Adjust seating if needed, and allow adhesive to cure fully before exposure to water.
