[sebhc] H8 connectors

[Dwight K. Elvey]

Hi Jack
 It sounds like good stuff. There is also a product that
one can get through HiFi shops but I forget the name.
The trick with any of these things is that they have
poor film strength ( don't make very good lubricants )
and keep the air from the contacts. One does have to be
careful. Some of these things can harm some types of
plastics. That is why I've stuck with the DC#4. I know
that is doesn't dissolve any plastics.
 The film strength issue is why ordinary petroleum lubes
don't work.
 Some of the products like you have here work better than
DC#4 in salt environments, like on boats. The DC#4 tends
to react and make a glass like oxide. If auto people are
using it, it most likely works wonders. This is about
the nasties environment that a person can thing of.
