The inlet area had been sceniced previously using the patching plaster over screen, mainly just to close-in the area alongside the tracks. When I decided that an inlet might look good, I mixed up a batch of Durabond 90, sprayed the surface of the old plaster with water so that it wouldn't draw water out of the new batch, then dumped it in and levelled it with a drywall knife. When the surface was reasonably smooth and level, I lightly dabbed at it with a damp sponge, which lifted some small crests on the still-wet plaster. Then, near the shore, I touched various areas with a moist (but not dripping) drywall knife: this lifted larger crests, and by pushing slightly away from the shoreline while lifting, then pulling a bit towards the shore, it was possible to create curling or breaking waves. The plaster has to be fairly stiff, so that it will hold the shape until setting occurs - you have to keep right on top of this, as setting starts very near to the end of the 90 minutes, and occurs fairly rapidly. Once setting begins, you can't make any more waves - if you don't like what you've done, use a scraper or putty knife to remove it all before it hardens.
Once the plaster sets, you can still knock off any parts that look too high or out-of-place, then leave it for a day or two, depending on the thickness, to fully harden. Once hardened, apply the interior latex house paint in the colour you choose. My colours were both from scenery work: the brown is my basic "dirt" colour, while the green is used on background trees. If you use more than one colour, apply them "wet" so that you can blend them somewhat where the colours meet. Once the paint has dried to the touch, you can use a smaller brush to apply white highlights to rapids or waves, using either latex house paint or a water-based modelling paint, such as PollyScale. Let all of the paint dry completely, at least a full day, before coating with urethane. I used Varathane Interior Gloss Diamond Wood Finish, water-based to avoid any reactions with the previously applied paint, and to keep the odour down, too.

You can by it at any hardware store or home improvement centre. Apply it with a brush, and try to not let it pool, as applications that are too thick may dry "cloudy". Follow the instructions on the can, particularily concerning re-coating - if you wait too long to apply the second and third coats, you'll need to sand the surface, and it's very difficult to sand "water".


:-D:-D The urethane is a clear finish, although it appears milky when you're applying it, and it says on the can that it's "non-yellowing". The water effects have been in place over two years now, and appear to be the same as when these pictures were first posted. The urethane is a tough, scratch-resistant surface, so it's easy to dust the "water" once in a while with a soft cloth. Because the Durabond is so strong, high points on the surface, like waves or rapids, don't easily break off when dusting, and the tough surface provides a stable and durable surface for times when you want to place your camera right on the water to get a better angle for a photo.
As for shrinkage, there is none: the Durabond 90 is very stable and the colour and finish are merely coats of paint, so there's nothing to shrink or crack. "Creep" up the shoreline is minimal, too, unlike many cast products.
I think this method should be do-able by anyone: all of the water scenes in this thread were done at the same time, and were my first attempt.
Here are a couple of overhead views of that inlet of Lake Erie:
