Plaster Mannequin

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.
I hate to tell you this, but everything I have tried failed over time IF you want to put the statue outside. For whatever reason, moisture somehow finds its way into the plaster which starts the disintegration process. That being said, I have made plaster moisture resistant which means that as long as the base or bottom is not sitting in direct contact with water, exposed constantly to water or the elements, it can be wiped clean with say a damp rag or have water splashed on it then wiped up without affecting the plaster.
To do this, I have used Varathane Outdoor non-yellowing, UVB/UVA protecting polyurethane and many thick coats. I've tried using the spray on application, but was unable to get it thick enough as I could by brush application. I have a plaster doric column base that sits on ceramic tile that frequently gets washed as it is in an entry and the water has yet to break down the plaster. The piece was first primed, then painted with acyrilic which also helps seal the piece. Then I applied 5 coats of poly on top of that. A similar piece that I used the same technique with, but had outdoors disintegrated after one rainy season. You can get varathane in any home improvement store and the price varies as to what size can or whether you purchase the spray.
