My fiancee recently purchased a small waterfall/water bowl from pet smart cause it was on sale. It basically takes water from a holding tank, to the top of some rocks and drops it into a holding bowl which fills up and over flows into the holding tank.

Do you think our BP would like this?

Also, we had to build up the sides of the bowl a little to stop overflow, we used children's modeling clay because
a) we already had it
b) its non toxic
c) it dries solid

Well I painted over the white clay with a textured paint and I'm just wondering what would be the best way to seal it so that the BP doesn't come in contact with the actual paint and so the paint doesn't seep into the water?
