G: I have taken a look at Dels floating plastic, and was not impressed ( no offense to April & Del). Basically, it calls for mixing the floating plastic with regular plastic before pouring. That seem like a whole lot of extra work, and I am not interested in extra work. I also have some MF floating additive, but have not tried it yet. I have heard too many stories about these bubbles and health risk. I keep telling myself that I will try it one day, but that day has not come. I am very interested in hearing more about these bubbles, as I am also trying to get the illusive floating frog. Saint.
