After removing and cleaning the driver side of the trunk lid, I prepped the center of the trunk lid with rubbing alcohol. Then I used a solution of soap and water to allow for adjustment of the template on the trunk. The template has a centering hole, and you measure its distance from the wing to ensure it's parallel. I measured several times before I squeegee'd it into place. Then I installed the adhesive letters in the appropriate spots on the template. I put them on as lightly as possible and measured again before I pushed them into place for good.
