American Marking's AM-X “Xylene based “opaque valve-activated markers produce fast-drying, permanent marks on metal, wood, rubber and glass.
* This marker comes with an extra tip for extra value!
The AM-X is made with a thick paint formula that is specifically formulated to provide a durable mark that is a long lasting, highly visible weather-and fade-resistant for outdoor applications. It is designed to resist fading and UV exposure, as well as weathering from wind, rain and ice. We actually have sample marks on steel pipe in our test yard that is still legible after more than four years of exposure to the elements.
