The Pro-Mark® capillary marker features excellent flow. Whether you need to touch-up 1 inch or 20 feet, the Pro-Mark® marker does it the first time and every time. The colors are the most fade resistant, the most resistant to color shift from top coating and have the best bleed resistance. The nib offers superior flow along with the durability needed to do all normal repair work. The nib remains usable for the life of the marker. Marks equally well with the edge, the bottom or the tip. Good adhesion to most surfaces and resistance to polishes are built into the Pro-Mark® marker.
