Tyson,
It is the "new stuff from WS". I will wait and see how this pour finishes, and then decide if another is required. I may paint in some "water plants", and add a final layer.
The "water" needs 24 hours to cure, according to the directions.
It doesn't set up hard, so it is not easy to be sure when to pour another layer. On this second one, I used a small brush, and water, to blend the edges into the banks.(it is water soluable) I will have to check out these areas before going further. I also tipped the diorama to get the "water" to flow into all the areas more quickly.
When all the "water" is done, I'll experiment with the "water effects"product, to create water flow around rocks,and other obstructions.
When I first saw the products, WS people indicated that 1/8" was the maximum depth. The directions indicate 1/8" at a time, with no indicated maximum.
I think I might add fish before the last pour...it is O scale.
