That guy at Dragon Con showed me a trick with a heat gun and a wire brush that saved my foam sword edge
I was about to trash a warped EVA foam blade outside the workshop on Saturday morning and this random Jaime Lannister in full armor walked over, said 'you're burning it too hot, let it cool slower', then spent 10 minutes showing me how to re-shape the edge with a damp towel and a metal file, so has anyone else gotten rescued by a total stranger at a convention who clearly knew more than the person teaching the panel?

Heat guns warp foam faster than anything if you hold it in one spot. The trick is keeping it moving about 6 inches away and watching the shine go from dull to slightly wet looking. Once it gets that gloss you pull the heat off right away because that's the point where the cells are opening up. A damp towel works because it pulls heat out slow so the foam can relax back instead of snapping into a new shape. Metal file after is smart too, it cleans up the crusty bit the heat leaves behind. Sounds like that guy actually knew his stuff.
