A large-top quality finish is usually realized only if the components are absolutely submerged in the solution, Even though this is not generally the case owing to drips that occur if the elements are hung to dry.

For big parts, dipping is a bad Option Because the tank size will become prohibitively pricey. Dipping is most often utilised in production and routine maintenance facilities.
