In an emergency, like being caught in a remote spot, or when you're really limited on tools & time there's always sacrificing a window. Those little Super Crew windows are pretty cheap & easy to replace. Insurance may even cover them!

Last time I was in Hawaii an elderly couple was waiting for help to come in a rather remote spot b/c they'd locked themselves out of their rental car. Hours later, as the sun was setting, they were still there after I'd hiked out to see lava flow into the Pacific. They looked exhausted & I convinced them to let me break a window for them. Within seconds they were sitting comfortably inside w/AC running & on their way back to civilization for some R&R.
