Wash the trunk lid with soap and water to remove all dirt, wax, and debris. Dry completely with a clean microfiber cloth.

Wipe the full mounting area with isopropyl alcohol using a clean microfiber cloth. Allow 60 seconds to fully evaporate before proceeding.

Before removing the adhesive backing, hold the spoiler against the trunk lid to confirm alignment and familiarize yourself with the correct positioning.

Peel the protective film from the 3M adhesive strips. Avoid touching the exposed adhesive surface with bare fingers.

Align the spoiler from center outward, carefully lowering it onto the prepared surface. Work slowly — once the adhesive contacts the paint, repositioning is limited.

Press firmly and evenly across the full length of the spoiler for 60 seconds, paying particular attention to edges and ends.

Allow 24 hours of cure time before washing, exposing to rain, or applying pressure to the spoiler surface. Full bond strength is achieved after 72 hours.
