Albedo 100 Reflective Spray HIGHLY REFLECTIVE | Invisible, light-reflective spray paint to keep your pet visible in low light conditions such as twilight and at night. SAFE FOR PETS | Horse & Pet Spray is easily washed off with water and soap or shampoo and does not affect the fur. EASY TO USE | Always spray outside or in a well-ventilated area. Shake the can vigorously for ~ 1 min and holding it upright, spray immediately with even movement from a distance of ~ 1 foot (shake can periodically during application). Clean the nozzle after use by spraying upside down for 1-2 seconds. BE SAFE, BE SEEN | Our recommendation is to spray on lower limbs or moving parts such as the tail to get the most out of the reflective properties, since headlights using half-beam tend to be directed towards the ground.
