Installation / Application:
- Difficulty: 2/5
- Estimated time: 60-120 minutes
Instructions:
- Confirm kit contents and compare new seals to the removed sections to ensure correct lengths and profiles.
- Carefully remove the old weatherstrip by prying out any retaining clips and peeling the seal from the groove; cut into sections if necessary for easier removal.
- Clean the channel and surrounding area thoroughly with isopropyl alcohol to remove old adhesive, dirt, and corrosion; allow to dry.
- Dry-fit the new weatherstrip into the groove along the entire perimeter to check alignment and determine any trimming points.
- If adhesive is recommended, apply a continuous bead of weatherstrip cement to the groove or back of the seal per the adhesive manufacturer’s instructions.
- Starting at one end, press the new weatherstrip firmly into the groove, using a trim tool or your fingers to seat the bulb and any retention ribs fully into place.
- Trim excess material with a razor or utility knife for clean joints; use masking tape to hold corners or butt joints while adhesive cures, if used.
- Allow any adhesive to cure for the recommended time (typically 24 hours) before closing doors or exposing to water; test door operation and inspect for uniform sealing.
