Abstract: A novel method for coating an object with a thixotropic material, comprising application of the material on the object to be coated and exposing the object and thereby the thixotropic material applied thereon to vibrational or repeated impact forces so as to temporarily liquidize the coating material. By the disclosed method it is possible to obtain an improved thixotropic material coverage of an object, particularly as regards narrow, difficult-to-reach areas such as gaps and crevices of closed cavities. A suitable field of use for this method is anti-corrosion treatment of car bodies.

Abstract: A spraying device for applying a coating material such as anticorrosion oil to the internal surfaces of hollow bodies comprises a spray gun provided with a front piece which is inserted into the hollow body during operation of the device. Furthermore, the device comprises a pump for feeding the spray material to the gun and a control device for controlling the gun, the pump and the introduction of compressed gas into the front piece. This gas is introduced in order to further atomize the spray material ejected through an atomizing nozzle of the gun and in order to support the transport of the spray material through the front piece. The control device comprises means for controlling the rate of introduction of spray material into the gun. As a consequence, the degree of atomization of the spray material leaving the front piece is variable.
