Electric Boat General Dynamics in Groton Ct used to tape the hull penetrations with “3m” Duct Tape when they removed something, we called it EB Green. One of the subs they were building didn’t detect the hull taped opening before sea trials and dove to test depth with no leaks on the tape. 440 lbs/sq/in and it held. Good stuff. Lasts forever.

Funny enough, I've heard that same story from three different bubbleheads over the course of the last 20 years. Came up when I mentioned to them my dear, lamented and very much purloined roll of EB Green ... that my Mom threw out while cleaning my room when I was off at college.

Each one, of course, claimed it happened on HIS boat.
