Qik Joe Polar Express will outperform others in it's class because of it's special time release formula. Qik Joe Polar Express activates quickly. In addition, the various components melt at different speeds, allowing melting to occur over an extended period of time. Qik Joe Polar Express offers a high degree of ice melting action because of it's high percentage of calcium chloride. The calcium chloride acts as a catalyst, activating the other components of this high-performance blend. Along with it's quick activation, it also has exothermic properties or heat generating action. Qik Joe Polar Express is an affordable way to prevent ice formation. To keep walkways clear in the worst of storms, Qik Joe Polar Express should be spread prior to snowfall to make shoveling easier and will continue to work down to a temperature of -15 deg F.
