I've used a good amount of the stuff. In MN I would always get it at Fleet Farm cheap for quarts. It can sit awhile on the shelves and needs a good stirring or like MN-Mark said get it shaken up well. I've still had to stir it sometimes. With a little thinner it dries quite flat. I've used the grass, green, and brown colors mixing them in come cases. I always brush it on. Works well for me, durable with little to complain about. Never used the spray. I agree the marsh grass is lighter in color than maybe it should be. With a little brown tint that could be made just right.
