ABSTRACT:
A marker post having a breachable coating for providing a visual indication of the presence of an object, with the marker post comprised of glass fibers supported in a resin containing a secondary pigment to provide an internal color to the marker post, and with the breachable coating containing an ultraviolet blocking agent, with the breachable coating having a principle pigment of a color that is the same or substantially the same color as the secondary pigment in the resin so that in the event the breachable coating having the principle color pigment is breached, the underlying secondary pigment in the resin will be visible through the breached coating so that a viewer observing the marker post from a distance will see the marker post as one color even though two distinct surfaces of the marker post are exposed.
