I just finished sanding and polishing my 10/22 barrel and it looks like it is SS never heard of stainless being blued before is this possible or did i just get lucky and get the look i was after ? Also what would you fella's recommend to coat the barrel with for a long term /semi ,maintanance free finish? Right now it has a generous coating of RIG grease on it,but am looking for a more permanent finish. Thanks
