Di_electric contact grease is a silicone product, which theoretically should not harden. There are many different brands of this product available. I would evaluate it's appearance at time of use. I use the semi-clear variety. I know of the type you speak of that Ford uses, and it's a white gel, with a paste like appearance. Probably a low grade product. Nothing lasts forever, but I still use, and endorse a good quality grade of di-electric contact grease. --- content22207 <brobertson@xxxxxxxxxxxx> wrote: > > > > But old dielectric grease loses its conductive > properties and becomes > an INSULATOR.
