All of the body additions (scoop/spoiler) are typically installed using two-sided tape. Up front, we’re going to suggest that relying solely on tape to keep parts adhered to your Mustang’s surface isn’t the best idea. We’ve seen parts uprooted by pressure washers or even high track speeds. Ford Auto Body uses an adhesive substance from 3M that is designed specifically for this purpose. Hector preps each piece with an adhesive-enhancing agent, and then lays down a thorough bead of adhesive on all of them.
