I have a custom built aluminum hard top and would like to insulate the cabin/cuddy area with blue board. Probably 1 inch. Any body got any ideas on what kind of adhesive will bond extruded polystyrene to aluminum? I bought some really expensive 3M spay adhesive but am afraid to use with the list of chemicals on the label. I suspect it will dissolve the foam. I also want an adhesive that will bond some marine carpet to the foam later on when I finish installing all the LED cabin lights in the ceiling.
