I used frosted glass plate on this 'sea effect trial'. Mixed Tamiya Clear Green and Tamiya Clear Blue 1:2 and sprayed under the plate 2 coats. Than sprayed only Tamiya Clear Blue over it when mix dried. Used Humbrol White enamel for waves over acrylic med. gel and cotton for bow wave. It is not so good but its good start for such details for me. I am happy with the result and I am planning to use same method for my future builds atm.
About sea effect, any additional ideas are welcome.
