Engadget is reporting that a new chemical coating, originally designed to repel toxic vapors and liquids from soldiers' uniforms, may be the solution to small waterproof electronics
. "The Ion-Mask is a special invisible coating that is chemically bonded to the device and repels water. It should allow waterproofing to make it into devices that are too small for the seals that are usually used to do the trick. Devices can have joins and gaps coated for a general level of water repellence, or have individual components treated for even more protection."
