In order to prevent rust from forming on the surface of the vehicle, we recommend you try using the 6 Quart Slip Plate from B/A Products Co. This concoction is formulated with a very high concentration of friction fighting graphite along with a proprietary binder system to provide a long-lasting dry lubrication for the heaviest loads. It has a complete dry time of 8 hours at 70°F (21.1°C) and a tack-free dry time of 60-90 minutes at 70°F (21.1°C). When applied and dried, it creates a dry anti-friction graphite coating that doesn't attract and trap mud, dirt, dust, or grit. Able to handle high and low temperatures with little change to performance, the Slip Plate is naturally hydrophobic and provides lasting protection from rain, snow, and mud to help fight rust and corrosion.
