Why does every one think I'm talking about petroleum
grease. Many high power connectors are protected with
silicone grease and still functioning with out a
hitch after 25 years. Their contact resistance still
measures less then the original dry contact resistance.
I put silicone grease on the contacts of the USART
socket, in my Poly88, back in 1979, to fix a flaky contact.
I have had no reason since then to add more. I used
the Poly88 just last week. If I'm addicted, it is just
for new applications.
