Dielectric grease

Blond moment here.

 

I am thinking of getting some dielectric silicone grease.

This is up to 400 deg F - and totally non-conductive.

 

Does this mean if I was to clean electrical spade connections and put this grease on spade and connector then connect them up, the grease would act as an insulator and stop good contact?

    No because there will be metal to metal contact in the plug / socket. The grease will prevent moisture ingress and stop them going poxy again. It's exactly what I do each time I clean up a connector.

    will the grease not leave a thin film on the contacts tho - reducing conductivity?

    Or as the connector slides on does it clear off the grease?

     

    *EDIT*

    Just found out that when connectors slide together the metal-metal contact displaces the grease and forms a barrier around stopping any oxidation/corrosion from happening.
