Two 5-7/8" (149.2mm) edges—firm plastic and flexible rubber—make spreading, leveling and removal of excess filler fast, easy and consistent on a variety of instrument contours.
Open-grained woods such as rosewood, mahogany, koa, ash and walnut have porous surfaces. Filling and leveling the pores leaves the surface smooth for applying uniform finish coats. Using a contrasting filler color can often enhance the appearance of the wood grain as well.
See the directions on your filler container for specific application techniques.
Wear protective gloves when working with fillers and finishes.
