Re: what glue for attaching foam insulation to the cabin interior?
I second the 3M spray adhesive. They make two strengths, use the strongest (I think it's called 90 or something as opposed to the 77). I've used it for foam sound insulation in engine compartments and it works great except for overhead which needs to be redone every couple of years.
