I have to admit I'm not sure of the long term effectiveness, but I have not found the protek products to be a real long term solution either. The fact that German technicians have used it for decades gives me some consolation. In regards to leather the following is taken from the Ballistol website: *Leather* *BALLISTOL* effectively protects leather against getting hard and dry, against water, insects and fungi. Residues of tannic acid in leather will be neutralised. Dry leather softens and gets elastic again with a dull shine. Bright leather can get darker. The typically smell of *BALLISTOL* will evaporate quickly. There will be no greasy film an the leather.
