It's a bad idea to use dielectric grease on any charging connector on a vehicle, it will attract dirt and make a perfect abrasive paste that will damage both sides.
I'll stand by my recommendation that people should buy a hardwired Tesla wall-connector for daily use instead of making due with the less robust mobile connector.
