Tired of defogging sprays not working or leaking out inside your bag. Well, try FogZero. It's not a spray, it's a cream. You apply it like wax on your car, rub a little on and buff with a clean cloth. Not only is it a defogger, it cleans the shield and can take out light scratches. Not only works great on shields but we use it for everything, eyeglasses, mirrors, auto windshields, motorcycle masks, dive goggles and more. We also sell the larger container but the small one lasts a very long time. No extra shipping on the small Fog Zero when purchased with your steel or sharpening order.
