I am trying to figure out a good proof of concept for showing off stuff I have created which is basically liquid plastic. The cool thing about it is (literally and figuratively) I combine the components to make the stuff and there is no thermal reactions and no need to apply heat to combine the materials. I have a paper stormtrooper helmet that I had created and used a spray bottle and sprayed it on, and it hardened into plastic, with a few coats it could be hard to tell paper from real molded plastic. First problem I found is the spray bottle cannot give an even coating over the surface, I think I have a solution for that problem. But now is this problem, what should I build to create a good proof of concept? Suggestions or ideas??
