Bought a $70 heat gun to shape EVA foam for my Mandalorian helmet and it was the best money I've spent on this hobby
I was using a hair dryer for like two weeks on my first helmet build and the foam kept springing back before I could press it into shape. A guy at my local craft store in Sacramento said to just get a basic Wagner heat gun for around $70 and I almost didn't because it felt like a lot for one tool. Turns out you only need it on low, wave it over the foam for a few seconds, and it holds the curve perfectly while you press it against a bowl or whatever form you're using. My second helmet came out way cleaner than the first and I finished the whole thing in one weekend instead of dragging it out. Anyone else have a tool that seemed pricey but ended up being worth it for foam work?
