Every time Frank comes up to San Francisco to work on a project, he criticizes our hot glue guns. So we had to visit his shop to learn about Frank's favorite hot glue guns. For this week's Shop Tip, Frank explains the difference between high and low temperature hot glue, and how he uses each. Find the glue guns here: http://www.mcmaster.com/#hot-glue-guns/=11e6spp Have a shop tip of your own? Share it in the comments below!
