The Carmel High Purity Paint Marker is industrial-grade paint that is safe to use on alloy metal, aluminum, stainless steel, copper, brass, nickel, pewter, and cast iron. The high-purity paint marks will not contribute to corrosion, weakening, or degradation when applied. The nib is valve-activated with a pump action mechanism. This marker comes in two sizes for fine and thick markings.
Directions
1) Shake well. 2) Press down on the surface until paint flows over the tip. 3) Begin marking.
