    Depending on the part one of two steps is nessessary.

    1. Do nothing, just bring it in.
    2. If the part is constructed of welded tubing where a closed airspace has been created we suggest drilling a small hole to allow draining ingressed electrolyte. This ingression of electrolyte is NOT a result of electrolyte passing through the walls of the metal but by seeping through pinholes created by inadequate welding.
