Re: [TCML] finishing a secondary - would insulating foam be a good idea?
true that the base material is a polyureathane, but there are additional
additives that cure the foam alot faster than a "paint on" material. And
lets not forget the propellant used to appy the foam. Its not nitrogen
for sure.... Very flamable stuff!! Plus the propellant gas is trapped in
the foam after it hardens.

Let's not loose sight of the fact that the material in question is basically the same stuff that most of us coat the exterior of our coils with - polyurethane. If it were a problem, it's probably more of a problem on the outside of a coil than in the inside.
But I wholeheartedly agree with the consensus that none of this is necessary.
