That is something that I always carry in any of my vehicles. A wreck that causes a "bleeder" Rip open and pour in. Medics coming back from Iraq swear by the stuff. They say that it will stop the femural (sp?) artery. Now apparently if you have to use the stuff, you will hear cussing from the ER doctor. It is suppposed to be a bitch to get out. I would rather be alive in the ER with the doc mad at me.
