[More Info]
A direct-fit windshield weatherstrip engineered for 2-door hardtop models, this seal features an integrated trim groove designed to accept steel windshield molding. It creates a reliable, weather-tight barrier that prevents water intrusion, reduces wind noise and vibration, and restores the factory look where the original rubber has aged or failed. Made from a durable, weather-resistant rubber compound, the seal holds steel trim securely in place while delivering long-term durability and simple installation for restoration and maintenance projects.
Features:
  • Fits 2-door hardtop models (verify fitment for your specific year and model prior to purchase).
  • Integrated trim groove secures steel windshield molding for a factory-correct appearance.
  • Durable, weather-resistant rubber compound resists ozone, UV and temperature-related hardening.
  • Helps prevent leaks, wind noise and interior water damage by restoring a tight windshield seal.
  • OEM-style replacement that improves fit, finish and resale value during restoration.
  • Straightforward installation with adhesive or clip-in fit; designed for repeatable, reliable seating.
Installation / Application:
  • Difficulty: 2/5
  • Estimated time: 30–60 minutes (plus adhesive cure time)
Suggested Tools:
  • Trim removal tool or flat pry tool
  • Weatherstrip adhesive (e.g., 3M adhesive)
  • Denatured alcohol or solvent cleaner
  • Clean rags
  • Scissors or utility knife
  • Masking tape
  • Rubber mallet (optional)
  • Gloves
Instructions:
  1. Remove the old weatherstrip and any attached steel trim; carefully pry out old seal and trim using a trim tool to avoid damaging the channel.
  2. Clean the windshield flange and channel thoroughly with denatured alcohol or an appropriate solvent to remove adhesive, dirt, and old sealant. Allow to dry.
  3. Test-fit the new weatherstrip and steel trim (if installing trim) onto the windshield flange to confirm orientation and fit. Trim to length if necessary.
  4. Apply a thin, even bead of weatherstrip adhesive to the flange or inside the seal channel as recommended by the adhesive manufacturer.
  5. Starting at the top center of the windshield, press the weatherstrip into the flange and work outward toward the corners, seating the seal fully into the channel. For seals with a trim groove, align and seat the steel molding into the groove simultaneously.
  6. Use masking tape to hold the seal in position and maintain contact while the adhesive sets. Tap gently with a rubber mallet where necessary to fully seat the seal without deforming it.
  7. Wipe away any excess adhesive immediately with a clean rag and solvent per the adhesive instructions.
  8. Allow the adhesive to cure for the time specified by the adhesive manufacturer (typically several hours to 24 hours) before removing tape and reassembling any remaining trim or glass components.
  9. Inspect the installed seal for uniform seating and perform a water test to confirm there are no leaks. Make any minor adjustments as needed.
