Military Spec Cavity Rust Inhibitor / VG-101

Amber in color, ValuGard Military Spec Cavity rust Inhibitor is a Manufacturer-approved, solvent-borne thixotropic, Corrosion preventative compound that, without drilling is fogged / atomized into cavity areas. It protects new vehicle hoods, doors, rocker panels, tailgate / trunk and frames against rust-through perforation. Unlike oil-based product lines, ValuGard Cavity Rust Inhibitor is a single application that does not need to be reapplied. We are confident about the long-term durability of ValuGard Cavity Rust Inhibitor because it has been tested and proven specifically against the liquid de-icing chemical brines used in many parts of the country.  

  • Many panels in cavity areas do not have paint, they have just bare metal.    VG 101 Cavity Rust Inhibitor creates a durable coating to protect these surfaces from corrosion (inside – out)
  • Warranty for VG 101 provides coverage against environmental corrosion (de-icing brines), this coverage helps “wrap around” factory warranties which are coverage due to manufacturing defects
  • Meets or exceeds Military Specifications for perforation corrosion, as well as shown to specifically resist liquid de-icing brines under toughest industry testing. Use the form below to ask us for more information about the Military Specifications and the testing VG 101 has undergone.
  • As a complimentary product with our Undercoating, ValuGard Cavity Rust Inhibitor will penetrate and protect areas undercoating cannot reach.  
  • Heavy Duty, long term protection provided by a Manufacturer-Approved product that is applied without the need to drill any corrosion-causing holes in your vehicle.
