Well I can certaily try again using the steel wool. Like I mentioned these are just junk barrels that I am using for practice. Just to be clear, the wire wheel I'm using is the one I use when I do rust bluing. The kind Brownells sells specifically for carding after rust bluing. I'm not using some type of wire wheel used to remove paint or something like that. I don't want people thinking I'm a complete idiot smile

Would you recommend diluting the Mark Lee solution. I've heard that some solutions are way to strong/aggressive ?
