I worried about that too. The stuff in the doors wouldn't matter since
there is a layer of plastic and upholstery. In the nose of course it would
because nothing separates it from the passenger compartment.
I've heated this stuff and put it into closed areas for several months
prior to using it and I cannot smell it.
My first car ('66 Mustang) way back when was fast returning itself to the
Earth in the form of a rusty dust. We welded in some new panels and I used
roofing tar to seal the welds (we spot welded it vs. solid welding) to keep
water out of the floors. That stuff REALLY stunk but after a while the
stink faded - even on hot days.
I would not suggest roofing tar (unless applied tot he outside of the car)
but there are many other materials related to roof repairs that I would
give a chance to. You can always seal roofing materials like my walk pads
inside plastic sheeting.
In short whatever works for you.
