For those of you who mount pre-laminated maps (coated on both sides), here's a question. Do you trim the foam core to the map itself, or leave 1/8 to 1/4" of plastic past it? Trimming to the foam looks better, but removes the encapsulation effect, so the only thing really mounted is the back piece of plastic, and the front can still separate. But leaving the plastic wouldn't look as good. What do you do?
