>>>Hi Gil
>>>Galvanic corrosion only happens when an electrolyte media is present. It
can any kind of substance, liquid or not, that dissociates into free ions
(clsassic definition).So its better do not use anything than using a grease
that you don't know if it is inert or not.
>>>Best choice... go straight to anodising. aluminum oxide is non conductive
also.
>>>Best regards.
