It is a heavy gel, perfect for shallow waters on colored backgrounds, and is particularly suitable for creating streams, riverbeds, and waterfalls. For the latter, transparent water is poured onto a smooth surface. Once dried, it can be peeled off and cut into shape. Water tones are available in transparent, Mediterranean blue, Pacific blue, and Atlantic blue. The material is colored with lightfast pigments. You can create your own shades by mixing in a Model Air color of your choice. Please also note that the surface you are working on will influence the coloration.
