Modles coat

I have bean preparing paper modles for investment by dipping
them in wax, and was wondering if clear acrylic spray would work?
If not acrylic, is there some kinde of arisol medium that I could
coat the modles in? I would like my castings to retain as much
of the surface texture of the paper as posible, and the wax
diping usualy maskes the texture. Any suggestions would be gratly
appreciated.

thanks
