The bell housing is arranged relative to the fluid reservoir such that a lower end of the bell housing is at least partially submerged in the fluid thereby sealing the chamber of the bell housing from atmosphere. The bell housing is arranged relative to the fluid reservoir such that the second surface portion of the workpiece is disposed within the chamber of the bell housing that is sealed from atmosphere. A method is also disclosed. An apparatus is also disclosed.
