[Spridgets] Under bonnet clearance

[Hal Faulkner]

My experience with using canned foam inside plastic is that it doesn't
work!  The solvent needs to be able to evaporate in order for the foam to
harden.  Sprayed it into a plastic bag and waited.  Several minutes later
when I touched it the foam all collapsed like a cheap Cappucino.  Left with
a plastic bag full of a sticky, smelly mess that may or may not have
hardened inside the garbage bin.  could try it inside paper, however.
