I work with Huglu shotguns frequently, I'm told they have a silver hardchrome finish on the receiver and black hardchrome on the barrel.Would like to remove this finish on the exterior for blueing but do not want to disturb the engraving by buffing.Also would like to keep the hardchrome on interior surfaces as it's good for corrosion resistance.Could case coloring be done without hardchrome removal?
Any advise would be greatly appreciated.
