Spray Foam tutorial
 

I am looking in to using spray foam in congunction with mat sound deadener in my car. Before I go hap hazardly in to this I was hoping to find some sort of tutorial, hopefully with pics, of someone using the spray foam. For example I am thinking about filling the open space in my car doors however have to consider how to do so without limiting the movement of my windows or window cranks. Anyone here of a tutorial?
