With the tub modifications finished, the entire underside was coated with Lizard Skin Ceramic Insulation. This single-stage coating sprays on easily with an air gun and then dries to a dull finish that will help seal the floor and act as a heatshield and noise barrier. The official definition is "an advanced, water-based composition of high-grade acrylic binders with air-filled insulating/reflective and sound-absorbing particles." We just hope it helps us hear each other in the cabin of the Jeep and keeps our passenger's boots from melting to the floor. It also covers all the fresh bodywork and gives the firewall and underbelly of the tub a uniform finish.
