Strong, flexible top coat Colorfix is a clear top coat reinforced with acryl which dries to a hard, elastic glaze, contributes a brilliant sheen to nail colour and fixes it, forming an extra protective shield against flaking. How to use After the final coat of nail colour has dried, apply Colorfix over the entire nail, including the underneath portion of the nail tip and allow to dry thoroughly. A second coat of Colorfix, a few days later will brighten up your manicure and make it last even longer.
