Have you used Iron Patina paint yet?
Do Dodson Designs used it to make this amazing farmhouse market sign out of a piece of wood. Get this she magically makes the wood look like metal!
Apply the Iron Patina Paint in the areas that you want the rust to show. I used a sponge to apply the Iron Patina Paint and just dabbed it on in spots. Immediately while the patina paint was still wet, I sprayed over the wet paint with the green patina spray. I made sure my board was lying flat when I sprayed the activator. This allowed the activator to pool in some areas and that’s totally what I wanted.
This process is easy peasy! Read the full tutorial here!
