How to make a waterproof paper

Hi everyone, I hope you like this - a waterproof and easy-shaping paper. I have tested this with my models, and it is OK. I wonder can it work on complex models or not. I want to create more and more beautiful, simple models which everyone can make. I am very happy when I receive your feedback to improve my channel better.
