i have a couple places like that in front of the b pillar what about those areas and for the area behind the b pillar can i fill it completely with foam or does the fist rule apply? i am pretty sure that i can but just want to be sure before i do it.

In front of B pillar two layers or 4mm, which ever comes first.

A door is one place, so inner skin and outer skin would be 2 layers of 2mm or 1 layer of 4mm total.
