Thanks again, Jav. Good info; I've got an idea for using it for shallow, slightly muddy water, in a 1/35th scale stream. Sounds like it should work well; resin takes ages, it's expensive, and you have to do the 'water' before anything else. And, in a contained area! Your method should be good for most things, and if you don't mind, I'll use it in the Diorama Guide, after I've tried it. I'll give you a credit for the idea of course!!
