Black natural finish for steel or iron exterior building parts
I am building a custom Arts/Crafts building and using exposed steel connectors and straps.
What are suggestions for a "natural, black" finish. Some connectors are on exterior.
Try 20 gm tannic acid [adv: item on
Amazon]/15 gm phosphoric acid/ 1 lit water(do it yourself rust converter [adv: item on
). It must be clearcoated
