Yeah I used aluma hyde II and put it a little thicker on the front part of the slide so it will hold up in the holster. Also put it thicker on the top part of the slide seeing it had lost its finished do to the german police holsters and having holster wear. Was not in bad shape for a gun made in 1/1980. Over 20yrs of service and still a great shooting pistol then again any police trade in is going to see more holster wear then shooting.
