Canode blue die spotting ink for locating high spots on molds and dies, matching bearing and gear surfaces, metal scraping jobs, as well as layout applications on metals. Canode inks are water soluble and simple to apply with a brush, roller, or sprayer. Canode ink does not bleed or damage metal, and penetrates oil coatings. Non-drying, non-hardening. Transfers clearly from one surface to another. Since Canode inks are water based, they can be easily wiped off with a damp rag. 1 quart; 32 ounce bottle.
