FS 365 is a blend of mineral oil, surfactant, anti-corrosion additives and water, forming a stable micro-solution that can only be separated by evaporation.

FS 365 acts as a corrosion inhibitor in two important ways:

  • In general use: By supplying a lubricant coating to all metal surfaces, which builds up as you re-apply.
  • In road use: Salt neutralises the solubility of FS 365 effectively sealing the coating in place.
