Jacquard Dye-Na-Flow is a transparent fabric paint with the consistency of water. It will stretch with spandex and not crack. The fabric will also be able to contract like normal. You need to let it dry fully and then set it with a little heat, but after that it is totally washfast.
You can definitely apply it with an airbrush if you want to spray it on.
