There is provided a press-fit lubricant composition comprising an unsaturated compound with an iodine value of 100 or more.

A liquid composition which has an excellent coating property at room temperature and is retained on a surface to be coated after application on the surface, and a terminal-fitted electric wire having an increased corrosion resistance using the same. The liquid composition contains a high-consistency material, a low-viscosity liquid having a kinetic viscosity of 100 mm.sup.2/s or lower measured at 40 C. in accordance with JIS K2283, and an adduct containing an acidic phosphate ester containing one or more kinds of compounds represented by General Formulae (1) and (2), and a metal,

P(O)(OR.sub.1)(OH).sub.2(1),

P(O)(OR.sub.1).sub.2(OH)(2),

where R.sub.1 represents a hydrocarbon group having 4 to 30 carbon atoms.

A synthetic lubricant, cleaner and preservative composition and related methods for weapons and weapon systems, comprising: at least one isomer solvent; Alox 2100 calcium sulfonate; and at least one base oil selected from the base oil group consisting of: group I base oils; group II base oils; and group III base oils. Optional ingredients comprise mineral spirits, alpha-olefins, synthetic calcium sulfonates, fluoro-additives, and common moellen degras.

A dry film lubricant composition includes: an anionic wax emulsion including carnauba wax and an anionic surfactant; water; a thickener; an organic solvent; a fluorosurfactant; a phosphate additive; and an alkaline agent.
