Dielectric grease is an insulator, if you want a conductive grease, use No-Ox-Id. Both are water/moisture barriers but act differently. You can coat the terminals and connections with a small amount of dielectric grease (silicone) to try and insulate them from water and stave off corrosion, just like you can use plain vasoline or any other grease, but if you coat the terminals and connectors themselves with enough of it, you can actually prevent your car from starting because of all the insulation you are applying between them there.
