Hi Fred.
I have used either
http://www.affordablequalitylighting.com/docs/electroshield.html or
http://www.krylon.com/products/uvresistant_clear/ for several years to
protect screw heads and terminal blocks exposed to the weather. The screw
heads and terminal blocks always remained clean and shiny for years after
application.
If I ever had to remove a spade lug or bare wire from one of these protected
connection points, there was usually evidence (beyond the obviously clean
contacts) that the sprayed-on product was still intact as it would cause
greater rotational force to get the screw started, resulting in a small
amount of the dried product drifting away from the area as the screw head
broke free from its resting position.
