About Paint and Ink Markers

Paint markers work well even on dirty, rusty, wet, and oily surfaces. They leave textured marks you can feel with your hand.

Ink markers work best on a clean, dry surface. Marks dry faster than paint and are smooth to the touch.

Both paint and ink markers are permanent.

Write on oily, wet, and rusty metal surfaces in welding, metal layout, and metal fabrication applications.
