Keg lube is a great helper for all manner of problems.
Well, not ALL problems.
Does great for everything with a seal. I only started using it a while back an it has been a big help.

You did catch the post, about a "duct tape dam" around the top of your Corny's, didn't you?

So you can flood all the connections with pressure applied, and all hoses hooked up, and not resort to submerging the Corny.
