Guys, when I make clear plastic, I don't add anything but a few drops of heat stablizer for 1 cup of plastic. When I heat it the first time, it comes out clean and clear, but if I let it set and re-heat later, then it turns to a pee color. How are you guys keeping it clear to clearcoat your baits? I'm using it to clearcoat my frog eyes on my frogs.
