I recently did an event and it happened to rain. I stayed out of it for the most part, but did get a few drops on my Latex Gamorrean Guard mask. The mask was darkened where the water made contact and left rings where it dried. You could see spots and places where the water ran down. Is there a way to protect the paint job. It's painted with Reeves acrylic mixed with latex. I mixed up a color match and retouched it, but I don't want to mess with this everytime I hit bad weather. Any ideas? I had no trouble with any of the other latex parts staining like the mask.
