Engineered for straightforward installation, it’s ideal for restoration and maintenance projects where reliable sealing and ease of use matter.

Installation / Application:
- Difficulty: 2/5
- Estimated time: 45-90 minutes
Instructions:
- Park vehicle on a level surface and work in a well-lit, dry area. Gather tools and the new seal kit.
- Carefully remove the old weatherstrip: pry trim away gently with a plastic trim tool and pull the old seal from the groove. Cut into sections if needed to remove trapped pieces.
- Clean the groove/channel thoroughly with isopropyl alcohol or an approved cleaner to remove old adhesive, dirt, and grease. Allow to dry.
- Test-fit the new weatherstrip along the trim groove to confirm orientation and length. Trim excess with a razor or utility knife for a precise fit.
- If required, apply a thin, even bead of weatherstrip adhesive to the groove or the weatherstrip as specified by the adhesive instructions.
- Press the new seal into the groove starting at one end and work along the length, ensuring the profile seats fully and consistently. Use firm hand pressure or a roller to set the seal.
- Wipe away any excess adhesive immediately with a clean rag and cleaner. Reinstall any trim pieces removed earlier and verify panel alignment.
- Allow adhesive to cure per the adhesive manufacturer’s instructions before exposing the seal to moisture or driving at high speeds.
