How to Make armor out or Sintra and Rub'n'Buff

Make your own armor with a weathered look out of Sintra (or expanded PVC foam). You'll need a heat gun, a padded cushion, paper towels, rub'n'buff in silver leaf, a knife, a marking pencil, water and a can of spray primer. Trace your piece onto the Sintra, then use the heat gun to shape it. Useful for costumes, Halloween or larps.
