I use Nu Finish in Crushed Walnut Shell Media in a RCBS Vibrator Cleaner and I am wondering if the Nu Finish seals the primers of loaded ammo? I am vibrator cleaning some tarnished ammo and using Nu Finish in the Walnut Media. I am thinking that the Nu Finish also seals the primer area of a loaded round, is my assumption correct or should I use a primer sealer? I know it is not necessary to seal factory ammo but I am wondering about this Nu Finish as a primer sealer of loaded ammo.
