Install tips (recommended)

1. Prep – Clean glass thoroughly with isopropyl alcohol and dry completely. Avoid installing in direct sun or on hot glass.

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

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

4. Remove transfer paper – Peel the transfer paper back on itself (180°) slowly. If any vinyl lifts, lay the transfer back down, squeegee again, then continue peeling.

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

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