Does anyone have any specific info on how Wilkinson did the frost etching on their swords? I believe they used some kind of paint as a mask and a weak acid as the etchant, but I have no clue as to what kind of paint or which acid they used, or if this is even the method they used to get that frosted look. Can anyone fill in the details or point me in the right direction?
