Waxoyl Professional 120-4 for Cavities

The Science behind Waxoyl Professional 120-4

  • One application protects for the life of the vehicle.
  • Where surface rust already exists, Waxoyl Professional 120-4 stops further corrosion.
  • "Fogs" the cavities to provide total coverage.
  • Penetrates deep into seams, providing protection where it is needed most.
  • Professional application tools snake through existing drains for complete protection without drilling access holes.
  • Displaces moisture to achieve an optimum bond, even in damp environments. Can be applied to wet surfaces.
  • A little goes a long way! Optimal protection with only .04 to .05 mm dry film thickness, resulting in a coverage area over 60ft square feet per litre.
  • Temperature range of active protection from -40°F to 300°F.
  • Safe on all paint finishes. Contains no silicones or fluorocarbons.
