Derek You might want to do some more research before you start. The process you are going to use for neutralizing the acid bath stops the etching process but dose nothing to stop the rusting process. It will continue to rust until you arrest the rust process and as far as I know (and I may be wrong) It will continue to rust till it is coated in oil. Brad uses an assemble line and steam to do barrels and he may be doing it from start to finish in a day. This greatly increases the speed at witch he can rust a set of barrels. That"s why I asked the question of him.
