This stick-on heat shield can reflect over 90 percent of radiant heat. HP Sticky Shield™ is the ultimate way to stop heat from radiating into the driver’s compartment of your ride. Made from a dense layer of 1/8-inch-thick proprietary Kool Core™ insulation and shielded by a rugged layer of 3 mil-thick aluminum, HP Sticky Shield™ may be cleaned after installation and is resistant to the elements.
