    So, lately my car has had issues starting up and usually disconnecting the cables from the battery and using a terminal cleaner wire brush on the cable and terminal will resolve it

    My question is using silicon spray a good idea to prevent any corrosion that I assume is making the contacts faulty from time to time. The lubricant is dielectric, which to my understanding is an electrical insulator but supports electric fields and thus should be fine...or am I mistaken?

    I would use an anti-oxidant paste, as is used for dissimilar wiring, i.e. copper and aluminium. It prevents arcing between the surfaces of the wires.

    I use the battery protector & sealer by permatex. Give the cables a good cleaning with a wire brush, spray that stuff on and you'll never have corrosion again.
