Abstract: A unitary drier for use in drying the under portion of an automotive vehicle having a vertically disposed forced air inlet duct, a source of forced air in cooperative association with the air inlet duct, means for heating the source of forced air to a predetermined temperature, and a horizontally disposed forced air dispersing duct connected to the air inlet duct that is capable of being placed underneath the automotive vehicle. The dispersing duct has a plurality of uniformly arranged forced air discharge means to discharge a uniform array of heated air to the under portion of the automotive vehicle whereby moisture is removed from the under portion of the automotive vehicle by the force of the heated air impinging on the under portion and by evaporation.
