I was watching a video on making trees for my N scale layout and the person in the video was using this glue on his trees.He mentioned using it as water on his layout because it dries clear.I have a stream running through my layout.It's all on foam board.At the moment I have the bed painted black.I'm looking for a way to add wet looking water and was wondering if anyone used this as their water on foam board?I wanted something lightweight,was thinking about 2 part epoxy but know that adds weight as I have used it on my mid power rockets.
