I read your excellent article about making gourd canteens. I am wondering how long would it last and how could I make it even more durable on the exterior and the interior to contain water. Would bees wax be enough to contain water for a month or two? And the exterior would need some type of coating? I would like to fashion my own canteens for excursions and expeditions.

Yes, that should work fine. As for the outside, a coating of polyurethane should be sufficient.
