Installation Instructions

Required Items

  • Clean microfiber cloth

  • Mild soap & water or alcohol wipes

  • Heat gun or hair dryer (optional, for cold weather)

-Step 1: Prepare the Surface

Thoroughly clean the roofline and upper edge of the rear window. Ensure the surface is completely dry and free of dust, wax, and oils for maximum adhesion.

-Step 2: Test Fit the Spoiler

Hold the visor spoiler against the roofline to check alignment. Use masking tape as reference markers if needed.

-Step 3: Apply the Spoiler

  • Partially peel back the adhesive tape liners at both ends of the spoiler.

  • Carefully position the spoiler using your reference points.

  • Secure the ends first, then slowly remove the remaining tape liner while applying firm, even pressure along the length of the spoiler.

-Step 4: Secure & Finalize

  • Press firmly along all edges to ensure proper bonding.

  • If installing in colder temperatures, gently warm the tape area with a heat gun or hair dryer.

  • Allow 48 hours before washing the vehicle or exposing it to heavy rain.
