any way to remove J-B weld?

I am just wondering how anybody gets along without a heat gun. I have a Harbor Freight gun that was on sale for $12. It has worked great for several years, and I truly use it all the time.
hell yeah, I even reflowed my PS3s graphics board with it, heats up great..not a bad little small space heater too. you can almost press piston pins with their heat.
