This invention generally relates to a spray apparatus and a method useful in the repair of coating adhered to can ends used in the food and beverage packaging industries. The sealing material comprises V+4. The flexible film is wrapped around two axes which are generally perpendicular to one another and preferably located within the same plane such that the flexible film covers at least a majority of the layer. Accordingly, when the screw member and the fixing side plate are attached to the insulator, the power connector corresponding to the power plug can be firmly assembled by fixing the track of fixing side plate into the slideway of latching slot. When due to instantaneous interruption of a power source supplied to the shift range switching apparatus, the shift range switching apparatus is reactivated, a target shift range is determined based on a rotation position of a detent plate detected by a detent position sensor immediately after the reactivation, and the rotation position of the detent plate is controlled. Users also compile the workflow via the application programming interface.
