Repel is used as a waterproofing agent for any fabric or suede. From raincoats to ties and even sued jackets and shoes you simply hold the can about 8 inches from the surface and spray an even application. Let the spray dry and you have a waterproof surface that's shower resistant. Its second use is as a spray lubricant for almost any application. Professional dry cleaners often use this to ease stuck zips (metal or nylon), but it can be used on hinges, locks, drawers and curtain rails with equal ease.
