A method for shaping an aerosol container () to a desired body contour. A container body () is formed into a cylindrical shape and installed into a mold () whose inner surface defines the desired body contour. A bladder () is fitted onto a tool () insertable into an open end (M) of the container body. Once the tool is inserted, the bladder is inflated with a hydraulic fluid. Pressurizing the bladder forces the bladder against a sidewall of the body forcing the body outwardly and deforming it against the inside of the mold. After the container body is shaped, the bladder is de-pressurized and the tool withdrawn leaving the container with a defined body contour. The hydraulic fluid with which the bladder is pressurized is, at all times, contained within the bladder and does not contact the container sidewall so no subsequent drying of the container is required after the shaping process is complete.
