DuPont™ ChromaPremier® and ChromaLusion® automotive finishes use high-strength tints and brilliant pigments to give Jeff's car a unique look in a variety of different paint schemes, including the "Fire & Flames" design. DuPont-patented undercoat technology also helps the paint cover faster and in fewer coats. Jeff's driving suits and gloves are made of DuPont™ Nomex® brand fiber - the same fire-resistant material used to make the turncoats that protect firefighters. Every member of Jeff's "over-the-wall-crew" wears the same type of suit to protect them as they perform their high-speed magic in the pits The front air dam on Jeff's car is reinforced with DuPont™ Kevlar® aramid fiber to provide better down force on the track without added weight. Kevlar® is stronger than steel on a pound-for-pound basis and is used in bullet-resistant vests. Teflon® PTFE is used for the extruded hoses and tubing that carry fluids through the crowded engine compartment of Jeff's car. The material is strong, lightweight and flexible, making it ideal for tight bends and cramped spaces. Metal needle bearings in the rocker area of Jeff's car have been replaced with DuPont™ Vespel® polyimide parts. Using Vespel® reduced the weight in the No. 24 car without sacrificing strength or pivoting performance. And because Vespel® needs less lubrication than metal, less oil has to be pumped to that part of the engine, freeing up a little more horsepower to get the car across the finish line faster. DuPont™ Krytox® performance lubricant is used to keep the rubber/silicone boot on the spark plug wires of Jeff's car from sticking to the plug's ceramic insulator. Krytox® stands up to intense heat under the hood, and is used on General Motors cars to solve this same problem.
