VpCI-329 is a vapor corrosion inhibiting oil-based concentrate for use with lubricating, hydraulic and preservation oils. It provides excellent protection in sheltered outdoor/indoor conditions. VpCI-329 protects in two unique ways by offering a tenacious film, which clings to metal surfaces as well as vapor phase inhibitors into the air above the oil. The vapors condense and form a protective barrier on metal surfaces that are not in contact with the oil. This combination allows complete protection to internal system parts. Spray, dip or brush onto metal parts before storage. Add to oil in engines before storage. For best results, add to the oil, then cycle or run the engine for 10 minutes before shutdown. After storage, the engine can be normally operated. There is no need to remove the VpCI-329 from an operating engine.
