A direct-replacement windshield weatherstrip designed for First Series GM vehicles (WBL 362). This seal (without a trim groove) provides a secure, watertight barrier between windshield glass and body flange to prevent leaks, reduce wind noise, and protect the interior from weather and road debris. Made from a durable weather-resistant rubber compound, it restores original fit and finish for restoration projects and reliable daily use while offering long-lasting flexibility and easy installation.
Features:
- Fits First Series GM vehicles — part number WBL 362 (windshield weatherstrip, no trim groove).
- Constructed from weather-resistant rubber for long-term durability and flexibility.
- Designed to seal the windshield opening, preventing water intrusion and reducing wind noise.
- No trim groove design for use where windshield trim is not required or when using alternative mounting methods.
- Ideal for restorations and replacements to restore proper fit and original appearance.
- Simple hand-fit installation — contours to the flange for reliable sealing performance.
Installation / Application:
- Difficulty: 3/5
- Estimated time: 1–2 hours
Instructions:
- Remove windshield trim and carefully detach the old weatherstrip and any remaining adhesive or sealant.
- Clean the windshield flange and channel thoroughly with isopropyl alcohol or adhesive cleaner; remove rust, dirt, and old sealant for proper seating.
- Dry-fit the new weatherstrip (WBL 362) around the opening to confirm orientation and fit; trim excess only if necessary.
- Apply a light film of soapy water or silicone lubricant to the channel and inside of the seal to ease installation (do not use petroleum-based products).
- Starting at the top center, press the weatherstrip into the flange channel, working outward and downward on each side; use a rubber or plastic mallet gently to seat corners and tight spots.
- If installing the windshield at the same time, position the glass with suction cups and carefully lower it into the seated weatherstrip, ensuring even engagement around the perimeter.
- Reinstall any trim pieces or retainers if required; use clamps or tape to hold the seal in place while adhesive (if used) cures according to the adhesive manufacturer's instructions.
- Allow recommended cure time for any adhesive, then check for even seating and test for leaks by gently spraying water around the windshield perimeter.
