Per Lancair a few years ago, the epoxy/fiberglass system used will not
support flame.  However, they start to loose shape, reform, etc. at about
180 degrees F (85C) and that is one of the major reasons for light color
paint so that heat build is kept to a minimum.  IF you haven't tried it, you
can reshape several areas like the door frame by heating, but not exceeding,
200 degrees.
