I’m also a fire guy so I’m unnecessarily against that stuff. It is a great product though, I just wouldn’t have it exposed in my ceiling. Its super flammable.

I'm not sure about painting spray foam as we have never done it, however I do know it 100% needs to be covered with a thermal barrier ie. drywall or a thermal spray. During combustion spray foam is highly toxic.
