No, but having used Eternabond tape on several projects, I would think it would work if the crack is not on the bottom or low on the sides. you must get the area completely clean for a good bond.

Clean the area with acetone or something similar that will not leave any residue. Eternabond will stick and seal the leak, but the area must be clean and tape applied properly. I have used it on several things other than moho and find it to do what it advertises. I beleive I read that eternabond was first designed for repairing underwater pipes.

You dcould be right about Eternabond developed for underwater pipes. i had heard it was developed for NASA. Either way, it works.

The tape is designed to seal from the outside. In your application the adhesive side is being asked to perform the sealing.
I bet it will work for a while, then start to fail at the leak point as the adhesive breaks down. The wider the tape the better in my opinion.

Another thought, not knowing the location or the severity of the crack. You might want to take a look at J-B Weld. It is an epoxy resin with hardener that I have used many times for cracks, bonding and leaks, even those under significant pressure. Once hardened, it is hard as steel and is impervious to water and most other fluids. Like most of these products, surface prep is absolutely critical to ensure a lasting fix. After it hardens, I would put the Eternabond over the area....as added insurance. If you have interest, send me a PM, and we can discuss it further. The stuff is available at auto parts stores and other retailers....and is not expensive at all.
Best of all, it works! Just a thought....
