You take a quick look around. You notice a truck with a camper pulled over to the side of the road with a blown out tire. You look into the locked camper. Theres a cooler in there. You pick up a chunk of burnt truck debree from your earlier violence and you use it to smash the window open. You open the cooler. Its one third full of mostly melted ice, still very cold to the touch. You heft out the cooler and you pour it out onto your weapon, a half city block disappears into steam and fog! You weapon is cooled down and ready to go now.
