The Nissen Penamark-S is a stick of paint in a solid form designed especially for fabricators. Marks placed on bare metal will bleed through the oil-based primer and remain visible. The penetrating action can be stopped, so as not to bleed through the final coating.

    * Marks on any surface: rough, smooth, wet, oily or dry.
    * Available only in blue.
    * Size is 11/16" x 4 1/2".
