What's the bet this stuff is an epoxy?

I have used epoxy laminating resins to make fiberglass casts of
fossil whales. Good stuff, much nicer than the much more common
polyester, but... it does tend to soften with heat. Strong sunlight
may do this. A cast, when warmed-up, is somewhat flexible... and will
not spring back to shape when bent. But in a seam this is hardly
going to be a problem.
