I second the Effax. Very effective. I prefer the Passier Lederbalsam over it though, because I just prefer the smell. I think the two perform about equally, I just like the aromatherapy effect I get while applying the Lederbalsam. With both the Effax and Lederbalsam, I? Rub it in with my fingertips and hands, then let it sit for 24 hours before wiping off the excess and buffing it out. The leather tends to be a little tacky for the first ride, then it's good.
