I flew 20 hours with these gaskets and they were still white when I took the flange off. My augmentor tube is made of aluminum. The part that is getting hit by the exhaust gasses, I laid a layer of FF and than thin layer of stainless sheet metal. The paint on the aluminum does not even change color.
