If it is possible to buy a product that will conduct electricity reliably and equally provide protection from corrosion etc, I would love to know where to get it. A little while ago I was looking for such a product to improve my Land Rover starter cable connections and voltage for the cold weather and did not find one. I think I read of a German product but I cannot remember the name. It may not be available on these shores anyway. Most products say in the instructions that care should be taken with electrical connections especially for high currents like starters as dielectric grease has basically insulating properties. I agree it gets used on electrical connections quite often but perhaps its best if smothered on after the connections are tightened.
