Prior to this, I used plasticine for seas, but this one is made from polysyrene foam. It was very easy to form the swell, I used a gas blowtorch with the air-intake turned off. This reduced the output to the level of a candle-flame. I then glued a sheet of crepe paper on top of it with white wood glue to give it a good painting surface. The paint was Humbrol model enamels. Very clean and successful - no more plasticine seas from now on! I was pointed in this direction via the "sea" section in "hints & tips!"
