I'm with brian on this. It can loom awesome or it can look tacky. All depends on the time you want to spend on it. I'm also a big fan of titebond/coco mix. And like brian said, practicing with that found can of gs would be a plus. You don't even need a spare tank to try it out, you can use a piece of cardboard if you want. Try making a big rock out of a big blob of the stuff. Remember, gs is about $3/can at walmart, so it's not like you are throwing a bunch of cash down the drain. I'd build ya one, but shipping would kill ya.......lol
