Default Dielectric grease

I plan on cleaning my ground connections. My question is do you think applying Dielectric grease is a good idea?

You can use dielectric grease on a ground or a conductive grease like Ox Guard…I would NOT use it inside low current carrying connectors like the Airbag or module circuits.

After cleaning the ground screw and connectors a coat of Dielectric grease will help keep corrosion at bay, and that's a very good thing.

Just remember it's a topical, not an interface material.

You can but it will attract a lot of dirt, dust and debris. You may want to try a dry film lubricant or even something like motorcycle chain lubricant, that will stay put and not attract dirt.

I also suggest the product NO-OX-ID for protecting exposed grounds.

Dielectric grease is an insulator, not a conductor, so do not put it between the metal contacts.

i grease (any grease) all my electrical connections. i have done a lot of testing on this and there is no change in resistivity when doing this. when you look up the electric conductance of a grease and realize how thin the layer is it will become intuitive. cleaning contacts (e.g. brake cleaner) is therefore unneccessary as well. an deoxydiser is good for old ones, though.

"dielectric" grease might be beneficial in spark plug boots, where it has the ability to form a substantial layer, but i doubt it. i use a coat of silicon grease to facilitate removal and maybe water proof the boot.
