Aida's the name!
i sanded the inside pieces and applied the Kilz primer and a clear top coat by Krylon. I then sealed the edges with silicone. i gave it a good spray down with that bleach water mix that's floating around here on the boards somewhere and its proved waterproof. Now if you have snakes that are prone to tipping over their water dishes, I'm not sure how it would withstand to pool of water sitting on it until you noticed it. the primer is a waterbased latex.
hopefully that answers the question you had.
