Composition capable of producing, by fast drying, a translucent film for the anticorrosion treatment of mechanical components based on ferrous alloys and, more particularly, of wrought components such as motor vehicle transmissions, characterised in that it comprises: - at least one calcium salt of oxidised petrolatum, - at least one overbased calcium sulphonate of formula: [R(SO3)b]2Cab,(CaCO3)a in which: . R is an alkylaryl group, . a, which is a positive number such that 1 < a </= 3, denotes the equivalent excess of basic salt in relation to stoichiometry, and . b is such that 1 </= b </= 5, the weight ratio of the calcium salt of oxidized petrolatum to the overbased calcium sulphonate being between 1 and 9 and preferably between 3.5 and 5.5. - at least one petroleum solvent, and - at least one antirust additive. b
