Detailing HPI bodies are now easier than ever: Use the factory-cut vinyl window masking to cover the inside of the car windows. Use your favorite RC car paints to detail the body as you wish, then peel off the outer overspray film. The molded-in body mount dimples tell you where to drill the body holes, and then use the included hardware to attach the wing! The factory-cut decal sheet features window borders, headlights, grilles and turn signals for realism, plus a complete set of racing decals for the "race car" look.
