         7 . The light duty lubricant of  claim 6  wherein the tackifier component is present in the lubricant in an amount ranging from about 0.3 to about 1.0 weight percent of a total weight of the lubricant.  
     
     
         8 . The light duty lubricant of  claim 1  wherein the ashless acidic rust inhibitor component comprises a reaction product of linear or branched alkyl or alkenyl substituted succinic anhydrides with imidazolines.  
     
     
         9 . The light duty lubricant of  claim 8  wherein the ashless acidic rust inhibitor component has a total acid number (TAN) ranging from about 50 to about 60 mgKOH/gram.  
     
     
         10 . The light duty lubricant of  claim 1  wherein the phosphorus-based corrosion inhibitor component comprises a reaction product of phosphorus with dimer-acids.  
     
     
         11 . An aerosol spray package comprising the light duty lubricant of  claim 6  and an aerosol component.  
     
     
         12 . A mist spray package comprising the light duty lubricant of  claim 6 .  
     
     
         13 . A method for inhibiting corrosion of a surface of a metal comprising applying a corrosion inhibiting composition to the surface of the metal, the composition containing from about 2 to about 5 weight percent ashless acidic rust inhibitor component, from about 25 to about 50 weight percent neutral alkaline earth metal sulfonate corrosion inhibitor component, from about 25 to about 50 weight percent phosphorus-based corrosion inhibitor component, and a process oil component.  
     
     
         14 . The method of  claim 13  wherein the composition includes a polyolefin tackifier component having a number average molecular weight ranging from about 1,000,000 to about 2,000,000 grams/mol.  
     
     
         15 . The method of  claim 14  wherein the tackifier component is present in the composition in an amount ranging from about 0.3 to about 1.0 weight percent of a total weight of the composition.  
     
     
         16 . A method for lubricating and protecting moving parts from corrosion comprising applying to the moving parts a corrosion inhibiting composition containing from about 2 to about 5 weight percent ashless acidic rust inhibitor component, from about 25 to about 50 weight percent neutral alkaline earth metal sulfonate corrosion inhibitor component, from about 25 to about 50 weight percent phosphorus-based corrosion inhibitor component, and a process oil component.
