don't get discouraged. avery is allergic to heat. I can never do a charger BG without burning it. The craftsman heat gun i normally use does get hotter than most guns though. anyway leave all the excess film and do the h pattern. use baby powder for maximum float on the BG (normally ppl use dryer sheets or bar soap). hold and stretch the end starting in the center and start shrking in large regions with long horzontal passes where ever you are heating the other hand should be pulling on the region. the film will lay do that for top and bottom and cut and wet check like normal. good luck!
