No it won’t. The connector still makes metal-to-metal contact, the Nye publications show that. What it does is to prevent moisture intrusion and helps to prevent sliding damage to the connectors especially if they are plated. There’s also a military study somewhere that shows the same thing. Nye used to have a really good publication devoted to this subject but they... “improved” their site and rolled some of the info into a more wide-ranging document.
You still want metal contact in the connector, not current flow though the grease. Dielectric grease does not prevent that.
Connector grease does not interfere with conductivity. Our test tutorials demonstrate the conductive and insulating properties of NyoGel® 760G.
