Cool. Hope it works. If not, there are a few other options. The simplest fix would be to paint the interior seams with Gluv-it, which is a spreadable, 2-part epoxy that dries tough, but flexible. It's usually available at West Marine and/or online. There is also another product called Coat-it which does the same thing. It will then need to either be painted over, or covered with a deck to give it UV protection. You can also rebuck/replace the rivets, or drill them out and replace the with small stainless steel bolts and nyloc washers dipped in 3M 5200.
