In the case of any particular treatment has to be subjected to modifications or require removal of only one treatment area, only the affected part can be machined mechanically by detecting the underlying aluminum. At this point it becomes possible to only deal with the interested area, leaving the rest intact.

It is essential that the work is homogeneous and clear to ensure an optimal end result.

Particulars in 7000 and 2000 alloys have greater risk of recovery, as they are more susceptible to a second re-immersion in galvanic bath.
