Im no guru, but i asked the same question a while ago but it was for painting my suite. As far as i know from what I been told is you can paint latex with acrylic paint as long as the paint is airbrushed and thinned down with Prosaide(or a similar adhesive) and water. Then you finish it by coating it and sealing it with PermaWet. Unless the rule of thumb is different with a mask. Look around the forums, dig through them and you will find answers.
