Instructions:
- Remove old weatherstrip and vent seals carefully using a trim tool or flat screwdriver to avoid damaging surrounding paint or trim.
- Clean the mounting channels and flange areas thoroughly with rubbing alcohol or a suitable cleaner; remove old adhesive residue and dirt.
- Dry-fit the new weatherstrip pieces and vent seals to confirm orientation and proper length; mark any areas that require trimming.
- If adhesive is recommended for your application, apply a thin, even bead of weatherstrip adhesive to the mounting surface per the adhesive manufacturer’s instructions.
- Press the new weatherstrip firmly into the channel or against the flange starting at one end and working toward the other to ensure a continuous seal; install vent seals in their designated locations.
- Trim any excess material with a utility knife or scissors, ensuring clean, straight edges for a neat appearance.
- Allow adhesive to cure if used (follow adhesive cure time); check door/vent operation and adjust seating if necessary to ensure a uniform seal and proper closure.
