A superior-excellent finish can be achieved provided that the elements are fully submerged in the answer, Even though this is simply not generally the case owing to drips that arise once the parts are hung to dry.
For big components, dipping is a nasty Resolution Because the tank dimensions results in being prohibitively high-priced. Dipping is most often utilised in production and servicing services.
