Harness the power of a Dragon's Breath in Bare Ground Dragons Brea Windshield Defrosting Spray. Easy to use 16oz aerosol can that utilizes a non flammable nitrogen propellant, Bare Ground Dragon's Breath uses the same potassium formate deicing liquid that airports spray on runways for a superior deicing that is the most environmentally friendly and gentle on all surface deicer available anywhere. It stores easily in your car for the cold mornings when your windshield is covered with ice and you just want to get going. Just spray on and watch the ice melt away. No need to turn up your defroster and let your car run to melt the windshield ice. Saves time, energy and the environment. Great for frozen locks too.consummable no warranty
