The Markal Galvanizer's Removable Paint Marker is designed for fabricators for making durable marks on steel during fabrication. The marks are then designed to be removed completely for galvanizers during the pickling process prior to galvanizing. This eliminates the need for any extensive, expensive, time consuming touch-up work. Features and Benefits Durable paint marks during fabrication.
