M™ Diamond Grade™ conspicuity markings series 983 and 3M™ flexible prismatic conspicuity markings series 963 are highly reflective and are pre-coated with an aggressive pressure sensitive adhesive for application to most clean, dry, wax-free, non-corroded, weather resistant surfaces. The adhesive is protected by an easy release liner. 3M™ conspicuity markings are intended to be applied to the side and rear perimeter of vehicles in a continuous stripe to enhance visibility and recognition by motorists. Markings can be applied to flat surfaces (with and without rivets) and non-compound curved surfaces with a radius greater than 5 inches. For application to corrugated vehicles apply the marking to the bottom and top rails or between corrugations if adequate flat surface is available.
