Impervious, The Universal Smartphone & Tablet Water Resistant Kit. Protects Against Spills, Splashes & Rain. Impervious protects your devices from LIQUID damage. Impervious is a spray that forms a microscopic protective barrier for your iPhones, Androids, smartphones, and tablets. Impervious is a non-water based solution that dries invisible to the treated surface. Impervious is also semi-permanent (lifespan of up to 3 years). Once applied, the proprietary formula will force liquids to bead and roll off the treated device. Also protects against paint spills, inks, milk, syrups, motor oil and other liquids that do not pass through this protective barrier. As seen on The Science Channels, All American Makers! Turn your Smartphone or Tablet into a water resistant device! No longer have to worry about water damage, spills or drops after applying Impervious!
