Was at Michaels last week hunting for EVA foam and this older dude walks up and asks if I'm making armor. I just nodded and he pointed me to contact cement instead of the spray adhesive I was holding. Said his son makes Mandalorian helmets and that spray stuff bubbles up after a week. Swapped to the brush-on kind and my chest piece actually held its shape after heat shaping. Anybody else get random tips from strangers that totally changed your build quality?
