ferric chloride Archived Message Posted by Al Limone on December 4, 2014, 5:06 am I'm refinishing my first set of Damascus barrels. I'm using ferric chloride from Radio Shack. Trying to get a 7% solution. From what I've read RS etchant is between 29% and 45% ferric chloride. If anyone has used it and can tell me how many oz. of fc to a gallon of distilled water I would appreciate it.
