My Kimber had some corrosion going on in the aluminum so I disassembled it completely, including the trigger assembly, firing pin, etc., cleaned it, and reassembled using Dupont Multi Lube. The wax coating didn't seem to build up, and the operation is smooth and not sticky. Although I haven't gone to the range to test it yet, I anticipate I will have flawless operation. Seems to me the Multi Lube or Amsoil MP (if they're the same) should provide great lubrication (moly) and protection (wax and corrosion inhibitors). Last, because of the thin wax coating it shouldn't evaporate, and if I remember correctly the moly should bond with the metal on the molecular level.
