After your piece is covered with the metal coating, if you’d like to add age to your piece, just add one of the patina's. These patinas also work beautifully on other metal objects.
There are also thirteen Swellegant DYE-OXIDES which are concentrated transparent colours. They act like patinas that soak into the other layers of your piece and transform all of the layers. All of the Swellegant metal coatings, patinas and dye-oxides can be layered in any order, as many times as you want. Experiment until you get the look you want
