Shake well before using. If mixing ball bearing is lodged in the solid, tap the base of the marker lightly on a hard surface to loosen it. Depress the tip to start the flow until the tip is saturated to the job requirement. Apply in the direction of the scratch and use a cloth or your thumb to wipe excess outside of the repair area. For worn areas, apply the markers along wear, wiping excess as quickly as possible before drying. Top coat if necessary once dry.
