You'll love the patina-like finish that you get on your projects when you use the Brass Art Extravagance Patina Paste by Finnabair for Prima. The package includes one 8.45 fluid ounce jar of paste that is water-based, archival and non-toxic. To use this thick opaque paste, simply apply the paste with a sponge, palette knife, texture tool or paintbrush. Use three different colors to create a multi-tone effect! The past is hard and permanent but flexible when dry.
