I am about ready to clean my closet out where I have a lot of stored acrylic paint... It seems that some of it is all dried out as the small containers of paint used for art projects were not air tight. The question I have for your is... Have you ever found a way to make dried out acrylic paint be usable? If so, how? or am I just going to have to toss it?
