Thanks Lars, but like I posted before this was my first water dio. So I was treading in uncharted waters myself, no pun intended.
Well to start I had to get styro foam and foam board since I had already made the ship with the entire hull. If you have the chance to make it a 'waterline' model do so. It's a lot easier. Once I measured and cut out the foam and made sure the ship looked natural in it then I airbrushed it with a mixture of Tamiya Sea Blue and American Acrylics Deep Midnight Blue. The beauty of the ocean is that you can make it as dark or light blue as you like. Once dried I placed the ship back into place and using Gel Medium (bought at Michaels) and a putty knife I formed the waves, the wake behind the ship, and the sides of the ship going thru water. Make sure to clean any unwanted excess off the hull of the ship. The Gel Medium is like white glue, it starts out white but it dries clear. I let it dry overnight and the next day I had a nice ocean looking display. Next I dry brushed the waves with Tamiya White. I especially made sure I gave the rear wake of the ship a nice dose to make it look like the foam of the ocean being churned up by a ships propeller. From there let your artistic eye take over. I hope this helps.
My grandson came over yesterday and I presented him with the finished Destroyer. He was ecstatic and he mentioned that it looked like the ship was on real ocean water. So know I'm thinking about making the USS Missouri as my next ship, but that will be later on. I was also thinking about the old German Pocket Battleship 'Admiral Graf Spee'; unfortunately I won't be able to post it here but I will post it on the FineScale Modeler website if I decide to make that. But that's in the future. For now I'll be jumping between the Iraqi desert and Khe Sanh, Vietnam.
