As the name implies it resists water. It is the only Pappy’s product that does repel water. I have tested it for several years, and it definitely helps prolong the life of leather exposed to moisture; as compared to other leather products I have used in the comparisons. It is made for boots, gloves, chaps and other things that are rained on or get wet from morning dew and everyday use. I use it on saddle back cinch straps and latigos, for the back side of the fender and stirrup leathers that comes against the horse, and for saddle strings that get wet from sweat or rain. Another use is for lubricating a cantle binding where the rope rubs, or the swells where the rope rubs. Treating these places helps the leather stay soft and move under the pressure of the rope. It helps to keep the leather from being so worn off from the abrasion. I keep the oils down so the leather doesn’t get soggy or sticky when used often. With all of these products if you get it in the tooling use an air compressor or brush and remove it before it sets up in the depressions. It polishes very well. It is slower drying than Pappy’s Premium Dubbin but repels water good. I would hate to be without this fine product. It may need to be applied weekly, more or less because you want some leather to resist penetration of water but also to breathe for comfort.
