When Tough Isn’t Enough—Go BOSS Combatting Corrosive Salt-Brine
Salt-brine solutions used for anti-icing on road surfaces can cause serious damage to your vehicle. The solution sprays on the entire undercarriage, leading to issues such as salt corrosion in wheel wells and brake lines, rubber degradation that can result in cracking, and brake fluid leaks. Over time, it can also affect the vehicle’s suspensions and paint. NHOU Mill-Spec BOSS WAX® & Oil serves as a protective barrier between your vehicle’s undercarriage and the elements, preventing rust and providing peace of mind that your vehicle is well-protected.
