maybe you could create some extra geometry on the out side.
Example, you might water running down the side of him, so just create a a subd cube, or a poly cube with lots of faces, so you can easily shape it. Scale it together so it has little thinkness about the size of water.
Add a phong material to it, set the colour to white, and slide the transparency all the way up.
set the ambient colour to white
Then play with the specular shading options to get the right kinda reflection.

hope this helps
