I really dont know how easily you can get to some of these tools but and easy way to fix is:
A peice of .040 thick aluminum 1" wide by the length of the area needing help, and bend it 90 degrees 1/2 X 1/2. The use a shrinker/stretcher and work it until the shape is right, and rivet it on. It would take about 15 minutes total to do the mouth and the upper part of the nose if the nose was off the car.
More than likely you dont have access to this stuff though, but to be helpful, I felt I had to throw the idea to the public.
thanks
