Use this kit plus the installation kit that came with your Gaurdian Comfort bedliner application to install your bed liner on top of a bed that has an existing spray-on liner. It includes (14) 1" x 2" hook-and-loop fasteners designed to stick to a spray-on bed liner. This installation kit also provides an adhesive promoter that you apply to the surface of the bed to help the hook-and-loop fasteners stick to the surface.
