Oh - did I not include that? I must go and check. Anyway, just use exterior grade old acrylic paint, so that it stands up to the weather. Try to have something black behind the screen that you paint, while you are painting it. A large piece of black paper or fabric taped to the screen works. It allows you to see what you are painting. If you try to paint the screen without something dark behind it, you really can not see what you are doing.
