Bear in mind that many of the chassis screws are used to secure 'earthing joints'. The use of a lubricating oil or copper slip will indeed reduce electolytic corrosion but may well also introduce some resistance, as all lubricating oils/greases will leave a thin skin even under pressure. However 'petroleum jelly' despite being a very good insulator has a lubrication factor of 1 and any pressure (via the screw threads) will break through the skin and make good contact. It will of course also cover the joint and limit corrosion. IMHO.
