Yeah, that's what I was doing that night in the rain trying to remove a flat that was torqued on to something like 250 Ft Lbs by the "management". Maybe I should have invited the knowledgeable mechanic out so he could stand in the rain with me while I beat his head all soft and mushy with the factory supplied wrench I also don't talk to "managers" anymore, I go for a district VP or the owner of the restaraunt that burned my food.

An inpact wrench is a wonderful invention. But tell me honestly how many people do you know that can operate one properly? I doubt you'll have to take that second hand out of your pocket except maybe to scratch your head.
