Wow, thanks Dan, talk about destructive testing.If you could ,I would like to see the pictures I am not sure how much pitting I am going to see once I do the electrolysis but would like to see an example of what to expect.My hope is that one might be able to salvage a set of barrels without having to manually remove a bunch of material(steel,iron) to maybe keep the integrity of the barrels intact and not thin them out to a no shoot point.Thanks Again,MY
