I read of one person's solution in regard to preventing further deterioration, but I haven't tried it yet. His method was to coat the bores with an automotive "Rust Reformer" product. Then, after drying, he would polish out the barrels. As I read it, the product contains phosphoric acid, and is able to stop further rusting by converting the rust to black oxide. The big caveat was that extreme care was needed, as any spilled on the exterior finish would prevent future bluing in those spots. Evidently he tried, but I'm not sure if he tried rust bluing or a cold blue solution.
