Now there are these nano-coatings defending against dust and scratches, with or without additional help of screen-protectors. There are nano-sprays available to simply spray on the screen for it to form a protective layer. There are also coatings available which are able to protect phones from submersion in water - even though the coating is then extended to the inside hardware, of course. My question, however, is whether such coating can be used to defend the MAO coating on the One S. A few major questions arise here - what coating would work, which one would adhere to the material? What will the feel of the coating on the material be, would you end up with a plastic feeling phone, let alone the look of it? Or would there be a spray which works in small amounts, only providing a very small but effective protecting layer?
