https://www.mgchemicals.com/products/grease-for-electronics/electrically-conductive-grease/carbon-conductive-grease/

846 is an economical carbon conductive grease that lubricates, reduces contact resistance, repels moisture, inhibits corrosion, and prevents static buildup.

Because of its high electrical conductivity, low cost, and ease of use, 846 is an ideal grease for electrical connections in applications like RV house battery terminals. It is excellent for ground connections, rotating connections, rotary switches, variable capacitors, roller inductors, roller bearings, slip rings, slide connecters and potentiometers.
