The beloved ArtInks now come in metallic shades! Use them as accent colors to create even more unique marbling effects! Use the provided Blending Fluid as an eraser or blender to disperse the layers of colors to create a variety of different patterns. Art Ink works ONLY on matte surfaces. Please apply a layer of Aprés Non-Wipe Matte Top Gelcoat over color gel before applying ArtInk and seal your design with a layer of Aprés Top Gelcoat for a beautiful, glossy finish!
