Built for Battle. Designed to Last.

  • Maximum abrasion resistance for long-term protection

  • Water-repellent & salt-blocking barrier

  • Stays flexible in extreme hot or cold conditions

  • Ideal for trucks, SUVs, off-roaders, and fleet vehicles

NHOU WHEEL-WELL GUARD - BLACK is brushed on areas that experience the most wear—like wheel-wells, running boards, and behind bumpers. The thick, matte black formula provides a self-repairing barrier against road salt, sand, and snow melt, sealing off oxygen and eliminating rust.
