When NH BOSS Wax is fully cured, it presents a non-tacky, extremely durable, and almost “elegant” black coating that will withstand the toughest environmental conditions. DIRECTIONS: Apply only to new vehicles—the surface must be dry, clean, and completely rust-free If the undercarriage has been exposed to road salt or liquid de-icing materials, wash with NHOU® Salt-Brine Eliminator™ (NHOU® Part #NHSB-1) and allow drying overnight Remove any grease from the undercarriage using denatured alcohol and a clean cloth Use aluminum foil, kraft paper, or drop cloth to avoid overspray on glass, painted surfaces, exhaust, electrical connectors, and fan belts Apply with an undercoating gun (NHOU® Part #7659) in a well-ventilated area, using an organic vapor air-purifying respirator Spray on all exposed surfaces, achieving 100% coverage with a minimum of two passes At 70° F, the surface will be dry to the touch in 1 hour (overspray coverings may be removed), and fully cured in 4 hours After NHOU® Boss Wax® has cured, apply NHOU® Clear Oil Undercoating to all cavities—avoiding exhaust system and rubber weather-stripping Clean equipment by circulating water through the spray gun and using a mild detergent on the vehicle’s painted surfaces 24-month inspections should be performed—reapplying NHOU® Boss Wax™ to any breaches in the surface and spraying NHOU® Clear Oil Undercoating in all cavities
