Air bubble's in my plastic?

[maniac]

Air bubbles are usually caused by moisture! You could have some moisture in the plastic you baught. You could also introduce air bubbles by using wood to stir your hot plastic. And as T.D said, there could be moisture in the colorant your using. If you add salt,then you will get bubbles , because the salt attracts moisture. microwave your salt before you add it to the plastic. Always put the lid back on your plastic container, when your not using it. If your using a 1 gallon jug then your probably shaking it as the method of mixing it, this will trap air in the plastic. You need to stir it, to make sure you get the hardener off of the bottom of the container. Try to stir it more and less shaking. If you over heat the plastic it will cause more bubbles, but will most likely burn the plastic causing it to turn yellow. don't store your plastic on cement, the cold cement can cause condensation when it's cold.
Good luck!
