A dispenser is provided for holding a quantity of the coating material and a delivery tip has adjustable bristles at one end. The bristles are slidably secured in a spiral passageway formed by an helical ridge inside the delivery tip, thereby allowing the coating material to be continuously applied without the need to stop the procedure and rewet the applicator. The applicator permits accurate control of the amount of coating material applied to the surface. In this way, the surface receives neither an excessive nor an insufficient amount of the coating material. |
