Rigid Foam Adhesive

[slager55]

What is the best caulk type adhesive for gluing rigid foam to the metal bus?

I used the poly-iso foam boards with a blue plastic coating on one side and a foil coating on the other. The Liquid Nails folks said I should use Liquid Nails for Marble and Granite and it worked real well on my build.

Here's mine with the flooring and insulation in. One thing I should have done was to seal the gaps between panels and around the windows to keep humidity from getting behind the panels. We haven't had a problem with it so far but we also don't produce much humidity either. I had to prop the panels against the walls and ceiling so the adhesive could cure overnight.
