The process described herein comprises an air drying solid film lubricant and the process for the preparation thereof and for applying the same to substrate metals. The air drying solid film lubricant comprises a binder and a lubricant, which binder consists essentially of a siloxane prepolymer having at least 10 repeating units of the formula MIXED IN AN INERT SOLVENT WITH AN AMINOALKYL-SILANE HAVING THE FORMULA AND THE LUBRICANT CONSISTING ESSENTIALLY OF A MIXTURE OF MOLYBDENUM SULFIDE (MoS2) and antimony oxide (Sb2O3), wherein R is hydrogen, alkyl, cycloalkyl or aminoalkyl of no more than ten carbon atoms; R' is a divalent hydrocarbon radical having at least three carbon atoms and having the valence bonds which are attached to the N and Si of the formula separated by at least three carbon atoms; R'' is a monovalent hydrocarbon radical having one to six carbon atoms; and N IS AN INTEGER HAVING A VALUE OF 0-2; SAID AMINOALKYL-SILANE BEING USED IN A PROPORTION OF 3-25 PARTS PER 100 PARTS OF SAID SILOXANE PREPOLYMER; SAID SOLVENT BEING USED IN A PROPORTION TO GIVE 20-40 PARTS SOLVENT PER PART OF BINDER; SAID MOLYBDENUM SULF
