Boeshield T-9 is a penetrating, waterproof lubricant and corrosion protectant for metal components. This version is the official 4 oz aerosol with manufacturer part number T90004. The current Boeshield aerosol Safety Data Sheet specifically covers T90004 and T90012.
Its low-viscosity formulation penetrates into pores, joints, fasteners and tight spaces while displacing moisture. The carrier solvents then evaporate over approximately 4 to 24 hours, leaving a thin lubricating and protective paraffin-wax coating.
