I learned early on from my dad and grandpa that heat was the ultimate weapon. Dad had an O/A set always at the ready, and he had no patience for stuck fasteners or parts. The torch was his favorite go-to option when dealing with rust. I was always amazed how he could handle that thing with such precision and not burn the surrounding area to a crisp. Grandpa was even better at it -- he was a "surgeon" with a cutting torch.
