My layout is in the basement, right next to the gas water heater and furnace. I've heard great things about Envirotex and other high gloss varnishes. But I'm not willing to risk blowing up my house, just for a nice looking lake and river. I'm wondering if woodland scenic realistic water is as flammable. I've heard it takes awhile to dry, but haven't heard whether the fumes need to be kept away from flames. I'm willing to go with gloss medium or chalk if needed. If you have any other ideas, or know whether realistic water is flammable (i.e. includes a warning on the label), I'd appreciate the input.
