Oh, it get's soggy all right!. At Comic-Con 2 years ago the humidity and heat damaged our cardboard Alphonse armor. The cardboard started to fall apart.
In this shot you see the brown cardboard peeling away from the forearm. Just the perfect effect for an interview with a japanese TV crew.
We made new parts from craft foam.
BTW, I recommend sealing the cardboard with a few applications of watered-down glue before using spray paint. Un-sealed cardboard can just soak up the paint. Seal correctly and you end up using less paint.
