Heat gun or blow dryer?

Actually the true thought is air FLOW as in volume (weight)

But good point. You might be able to take an old dryer and restrict the intake air to raise the outlet temp. You also might end up with a blob of useless plastic (dryer) LMAO

I tried that Too. It just blows the thermister-fuse inside.And when I jumpered it, I had to remove the screen so I could get real close, and then, The miserable thing set stuff on fire, all the while smelling like a rendering plant.lol
Then one day, I found a really old hairdryer at a garage-sale. It had a metal body and appeared to be from the 60s or 70s. That sucker could blow hot air! And the metal body was perfect for the toolbox. I haven't seen it now for a very long time;Gee, I wonder whatever happened to that beast.
