Yes, those are the metal coatings. Apply a coat, let it set up, then apply a second coat. Immediately after spray with your chosen patina. The longer it sets, the more oxidation you get. Sculpt Nouveau has many videos on YouTube that are definitely worth watching. Once I got started, I found it a fairly quick and easy process.Great info, and thanks! I'm intrigued by the dry brush iron coating you mention. Is this the type you used? http://www.sculptnouveau.com/Details.cfm?ProdID=42#skus I was thinking "Type B" sounds good. So it actually creates a metal coating, to which you can paint the patina finish? It really looks amazing. Thanks again!
