You are installing the engine turn on black opaque abv? This would be a second surface application; not adhering directly to the vehicle. Although the engine turn is a 5 year product (make sure you buy the 5 year product), I would laminate with an edge overlap to make sure the laminate encapsulates the engine turn. This is not the best installation because the black opaque and the engine turn will "shrink" at different rates over time.
