Would Plasti-Dip waterproof poster board?

Plastidip is aerosolized rubber coating. It can 'resist' rock chips...however, the more layers you put on, the tougher it gets. I have about 6 layers of plastidip on my bumper, and after 3 months of driving, i see a bunch of little rock "flecks," but nothing has penetrated the plastidip yet.
It's also difinately water proof. There is a youtube video of someone plastidipping a regular cardboard box... filled the box with water...no leaks.
