In order to maintain the long term reliability of an electrical connection subjected to difficult environmental conditions, such as in the engine compartment of a motor vehicle, a paste-like preparation is provided for application at the conductively mating surfaces of the connection. A first embodiment of the preparation includes water, glycerin, a thixotropic agent and a hydrophilic substance, such as calcium chloride or lithium chloride, exhibiting sufficient hydrophilic action and in sufficient quantity as to maintain the preparation in a fluid state by absorbing moisture from the ambient atmosphere. Variants of the preparation include, as one or more additional ingredients, acetic acid and/or powdered graphite or metallic powder or flakes of high conductivity such as copper, aluminum or silver. A second and presently preferred embodiment of the preparation includes detergent, ethylene glycol, fine sand and powdered graphite in conjunction with a high concentration of calcium chloride or lithium chloride.
