So I have a lot of ideas for various kinds of accessories but I am nervous about what materials will hold up underwater and what wont. Has there been any products or materials that you thought would be fine but didn't work out?
I am wondering what would happen to EVA foam of various thicknesses. What about wire? Hemp and rope? What about vinal and other super synthetic fabric?
Also, semi off topic, but has anyone ever used those waterproof pens and notebooks or tried them actually fully submerged?
