Install Tips (recommended)

1. Prep: Clean glass thoroughly with isopropyl alcohol. Dry completely. Avoid installing in direct sun or on hot glass.

2. Position: With the transfer paper (pre-mask) still on the decal, test-fit and hinge with painter’s tape.

3. Apply: Starting from the hinge, squeegee firmly from center outward using a felt-edge squeegee or card wrapped in microfiber. Use light heat if needed to help the vinyl lay.

4. Remove transfer paper: Slowly peel the transfer paper back on itself (180° angle). If any vinyl lifts, lay the transfer paper back down and squeegee again, then continue peeling.

5. Set & seal: After the transfer paper is off, do a final squeegee pass and light heat along edges.

6. Cure: Avoid washing the car or using window cleaners for 24 hours to allow the adhesive to set.
