So my old cooey model 75 barrel is fairly rusty and I want to polish is and reblue it. Its only a .22 but its just a small project that can take up my evening. Anyways, long story short, I was thinking about using a sanding disk or a flapper wheel (air tool) ever so lightly to remove the rust and old blueing (if there is any) and get it down to a stainless steel look then polish it and reblue or maybe just use a metal polish to shine it up. Like i said its just a .22 so it doesnt have to be show room quality, just something thatll look nice in the rack. I'm not really knowledgeable with brands of polish or anything so im open to suggestions!
