I used the white to build some reptile pens, and it worked really well. I built these as practice to build some aquariums, since I had some big pieces of 3/4 inch glass given to me. The white is nice for the reptile pens since it reflects light and is easy to clean - easy to see when its dirty. Black would have to be used though in an aquarium, black backgrounds painted on glass aquariums are really nice.
The reptile pens I use double pain windows given to me, so I cannot test if they would hold water. Well, the bottom is a huge plastic tub, so that would not hold either.
I am holding off, which is easy to procrastinate anyways
