My buddy swore by using a hairdryer for heat shrink tubing and I thought it was a bad idea

My buddy Mark bought a pro heat gun for his model trains. He used it twice before his girlfriend's cheap Conair took over. That thing lives on his workbench now, and the expensive gun is still in the box from three years ago. He says the hair dryer is just faster to grab and does the job fine. It's funny how the simple tool wins out most of the time.
