The STIFFIE Whipline™ SUPER STICKY Alpha Numeric Identification Kit is formulated with an extra aggressive adhesive to meet the demands of the Sea-Doo SPARK and its recycled LSE plastic construction. This model number will also work with your Inflatable Boat, RIB, Hypalon/ PVC boat as well as any standard PWC or Boat hull. If you need or want extra grip for your registration numbers then the STIFFIE Super Sticky registration decals are the way to go. If you are applying these decals to an RIB, no plastic plate will be required UNLESS you are going to DEFLATE the boat. The WHIPLINE style is a two-color registration decal features a flowing brush stroke design with a rounded cursive font style. The characters all slant forward and the exterior color fades in from the bottom over the interior color. The exterior outline color is heavy which allows for character over lapping, enabling you to create a unified, custom look like never before. STIFFIE decals are made to match your OEM Boat, Marine Vessel or Personal Watercraft using our COLOR CLONE™ print system.
