If the work is done properly the only one who will know it was done is you. Pick a competent craftsman and you should be good to go. Rust blue is not rocket science despite what some folks will tell you. Additionally, a good craftsman will most likely improve upon the factory barrel striking. The last few AYA barrels I polished out were not exactly well struck to begin with.
