How do I waterproof plaster of paris?

I need to waterproof a mannequin constructed mainly of plaster of paris. I need to know what I can use, where I can get it, directions, and if available, approximate price. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
