This example shows that a considerable amount of savings in time and money can be achieved by using the brush plating method.

The shaft is not subject to any heat distortion and the work is carried out in situe.

One of the most expensive issues in this type of repair is the down time.

By using the selective brush method most of the stripping down is not necessary.
