Splash! Not a sound you want to hear when you are handling your expensive electronics. I’ve had too many mini electronics like cell phones and cameras go in the drink. Generally toast. Not much you can do for them. By the way, if this happens to you, immediately turn the device off, remove the battery, invert the unit and let it dry out. May people report a day long immersion in dry rice can help remove the moisture. Sometimes you can be lucky and no damage is done.
Now the Liquipel company offers a coating service that offers a “self-sealing intelligent coating.” This miracle substance coats the internal electronics and wiring so no moisture gets in to affect the electronics. Liquipel states the highly advanced coating makes both the exterior and interior components waterproof, and it permanently bonds to your device on a molecular level!
They also state it will last the the life of your device. The coating used is 1,000 times thinner than a human hair, meaning there is no added bulk to your particular device. Service for a smart phone is $60 while a 10 inch tablet would run $80. They even coat earbuds so they work underwater for $30.
Liquipel claims that a mobile device can be submerged for 30 minutes at 3 feet and be fully functional. Liquipel also offers on their website iPhones and Samsung Android units pre-coated and warranted, I assume.
