How to Weatherproof new shoreline power cord connectors

Interesting topic and products shown here.

But like any ordinary extension cord, I have no worries about plugs not being sealed as long as they are not in standing water.

Consider all the outdoor Christmas lights people set up...and how many non-sealed plugs are out there in the rain and snow.

That said, I'm not saying not to seal corded connections. Obviously it added a high degree of safety.
