I have tired several methods and like the heat gun second best. Kengore is right on target with using the less heat principle. What I found very very good is a 100 watt spotlight bulb mounted in the bottom of my drying cabinet. I simply set the end of the reelseat on the top of the light bulb, go do something else for about 10 or 15 minutes, and they usually come right off. I am sure that there are a lot more methods out there that work equally as well, never hurts to know as many of them as you can!
