I also use it to fill in chipmunk holes on my lawn. I take a piece of
plywood, make a hole in it just big enough for the great stuff straw,
cover the hole and empty the can. It must go quite deep and fill all the
areas.

re: Are there any fundamental differences between the Fireblock foam,
door and window foam, cracks and gaps foam and big gap foam?
There are differences in the expanding properties of the different
brands/types. There are "expanding foams" and "minimal expanding
foams". Polyurethane foams and Latex foams. There is also Foam
Pressure to consider. Low Pressure does not necessarily mean Low
Expansion.
For example, take a look at the Great Stuff Window and Door compared
to DAP Window and Door.
Great Stuff says to fill the cavity to 50% to allow for expansion, DAP
says to fill to 90%. (I just did a window with DAP and I can attest to
the 90% number.)
I've heard of issues with some foams actually bowing the frames of
vinyl windows due to over-expansion. DAP is supposed to be safe in
that regard. There are other brands such as Hilti to consider also.

Depends on how soon after they start the car. They could just blow it
all out if it's still wet.

That's why you use a long extension tube that will reach way
up in there to the muffler. *snicker*
