12. Here, Wise is beginning the Vortex application process on the new LMC Truck tailgate. The Vortex material is pumped out of the machine at a very low 8 to 10 psi, and it hardens to a slightly tacky feel in about 10 seconds. Vortex can be applied to a variety of surfaces as long as the surface temperature is over 50 degrees Fahrenheit. He coated the inside and upper lip of the tailgate to offer maximum protection.
