Gork’s GoodFilla CLEAR Grain-Filler is a unique, patented, non-toxic, zero VOC, water-based product that allows the user to easily and efficiently fill the open grain. GoodFilla CLEAR Grain-Filler is non-film forming, reversible, and works with any finish to achieve a flawless end product. It is non-shrinking and stainable and can be applied between layers of finish without impacting adhesion. For wood with large open grain, CLEAR may be mixed with Gork's GoodFilla Paste Wood Fillers or wood flour. GoodFilla CLEAR may also be mixed water-soluble pigments and dyes to add color to the surface.
