Golden Shellback is a coating that lets you spill, pour, or submerge your gadget in a liquid and have it survive. Golden Shellback says it will protect against oils, water-based liquids, synthetic fluids, dust and dirt. Tekzilla's Patrick Norton shot a segment on Golden Shellback and has footage of cellphones and CB radios functioning normally under a foot of water (Golden Shellback claimed the CB sat underwater for 455 consecutive hours).
Apparently, the coating is applied in a vacuum and covers both the inner and outer components of a gadget, which doesn't conduct electricity. Golden Shellback hopes the protective coating will be available soon, and expect the service to cost between $50-$75 depending on the size of the gadget. But seeing is believing, so you should watch the video, which is borderline mindblowing.
