Toss all your rusty armor over your stained clothes and go show it off! I wish I'd had time to do makeup appropriate to the rest of the grit in the costume, but I suppose that will have to happen next time.
A couple tips about storing your Wonderflex armor:
Do not store it in a position where it is being pressed down on or where there is anything flattening the shape out. It should keep its dimensions quite well on its own, but after enough time and pressure, the curved edges can distort.
Store it in a temperature controlled space. No attics, garages, or outdoor storage lockers. Heat will distort and damage those shapes you worked so hard on!
DO NOT LEAVE IT IN YOUR CAR, EVER. See "heat damage" above
Beyond that, enjoy your durable and (relatively!) inexpensive costume pieces!
