OK so I screwed up the coating on my M44 while cleaning out the chamber with brake cleaner! At least the chamber and bore came out good but now due to dripping cleaner, the stock finish came off in some areas! I would like to restore it without too much hassle. The good areas are reddish brown and the striped areas are light tan. What is the original coating? My Russian model appears to be a recent reconditioned on from Classic Firearms. Thanks
