A durable windshield weatherstrip designed for hardtop, sedan, and wagon body styles where a trim groove is not used. This WBL D646 seal provides a watertight, weather-resistant barrier between the windshield and body, preventing leaks, wind noise, and water intrusion that can damage interiors and electronics. Molded from premium EPDM rubber for long-term UV and ozone resistance, the profile installs as an OEM-style replacement for restoration and maintenance projects. Its no-trim-groove design fits applications that require a clean, flush finish and reliable sealing performance.
Features:
- Designed for hardtop, sedan, and wagon body-style applications without a trim groove.
- Premium EPDM rubber construction resists UV, ozone, and temperature degradation.
- Seals windshield to body to prevent water leaks, drafts, and wind noise.
- No trim groove profile for a clean, flush installation where trim is not used.
- OEM-style fit and finish ideal for restorations and replacement projects.
- Easy to seat and trim for a precise fit; long-lasting durability for maintenance use.
Installation / Application:
- Difficulty: 2/5
- Estimated time: 30-60 minutes
Instructions:
- Park vehicle on level ground and protect painted surfaces with masking tape or cloth around the windshield area.
- Carefully remove the old weatherstrip: pry out the seal using a plastic trim tool or wrapped flat screwdriver, working slowly to avoid bending the windshield or damaging paint.
- Clean the channel and surrounding flange thoroughly with solvent or isopropyl alcohol to remove adhesive, dirt, and old seal residue. Allow to dry completely.
- Test-fit the new weatherstrip along the windshield opening to confirm orientation and length. If the seal is longer than required, mark trimming locations.
- If the fitment or vehicle service manual calls for adhesive, apply a thin, even bead of weatherstrip adhesive to the channel or seal lip per adhesive instructions; many applications will seat without glue but adhesive improves long-term hold.
- Starting at the top center of the windshield, press the seal into the channel and work outward toward both hood sides, ensuring the seal lip seats evenly and fully into the flange. Use firm hand pressure or a soft roller to seat the rubber.
- Trim any excess material at the corners or ends with a razor knife for a neat finish. Re-check the seal around the entire perimeter for full engagement.
- Allow adhesive to cure as specified by the adhesive manufacturer before exposing the vehicle to moisture or driving at high speeds. Recheck after first rain to ensure there are no leaks.
