Bob, this plastic material that you used for water does look like the real thing.
I like the last photo above, the light shining through it gives a rippled texture under the water, very effective in making it look like it's actually underwater.

Bob,

You are indeed a master of illusion. I am amazed at the creativity you display in everything you do.

I am confident you will some day find a use for the purple plastic sheet.

Mike

Thanks for your comments guys. While that material seems to be no longer available or cannot be
found, there is an alternative. Make you own. I'm going to give you two examples, one quite simple
and the other a bit more involved, but both well withing the abilities of all you great model
railroad modelers. The subject were not railroad related but the modeled water still applies.
It will be easier to post them in separate posts.

The simpler method. This model was built for the submarine museum at Groton, CT. The water was
made from a plain piece of acrylic sheet (any building supply store). The waves were built up
with several applications of acrylic gel medium ( any art store) and the bow wave and wake were made
from 5 minute clear epoxy glue. Then the BOTTOM of the sheet was painted with two applications of
a blue glaze, I used Creamcoat by Delta transparent wood glaze #4502 blueberry ice.

Note that you can see the hull down through the water's surface.

Hey, Bob! I've seen that model at the Groton submarine museum. Neat!
Did you slice the model and glue it to both sides of the acrylic or cut a hole in the acrylic and hide the edges with the gel medium and epoxy?
I've seen both ways, just wonder which you prefer?

Bill, I cut a hole in the material to fit the model. It has been my experience that doing so
beats slicing the model, subtracting the thickness of the plastic water, slicing that thickness off
the model, and lining up the bottom piece, every time. In my article I explained how to cut that
hole quite close to the model profile easily.

To explain the other method I will use a diorama I did on commission for one of the divers who was
actually there for the recovery of the Gemini Astronauts, based on a newspaper photo of the
event. To start I took a piece of aluminum foil and loosely crumpled it up into a ball. You could
use regular foil and spray it to keep some resin from sticking to it but the newer non-stick foil
"RELEASE" works much better. Open up the aluminum ball but do not press out all the wrinkles. I
mixed up a bowl of Envirotex Lite pour-on-gloss finish #2016 (at hardware and craft shops). I
then mixed in some Castin Craft resin dye, swirling in blue and green (craft store).

Lay out the foil, non-stick side up, and turn up the edges to form dikes. Pour the colored resin
onto the foil and if you do not need a lot of strength, let it harden. If you need variations
in color, I needed to make the water at the nose of the capsule much greener because they released
some dye marker to be seen easier. If you have a large area and need strength you can lay a sheet
of clear acrylic sheet over it, it will adhere to the resin and become the bottom of the surface.

In either case, after the resin cures you can very carefully peal the aluminum foil away. and
pin holes or bubbles can be filled with quick set epoxy glue. All detail such as rough water (I had
to show an area of disturbed water caused by the rotor wash from an unseen helicopter overhead)
with clear epoxy glue, acrylic gel medium, acrylic caulk, in any combination.
