You’re not a Debbie Downer, you’re a realist. I agree with everything you said. Also, spray foam is an insulator. Just stick your arm into a box filled with packing peanuts and you’ll feel how warm it gets. I couldn’t image wearing a foam insulation mask for more than 5 minutes. This would be great for props though.
The style of the one he made makes me think of The Ghost Galleon movie.
