zCover keyboard skins are printed with the default US keyboard layout in regular or large print, the Dvorak layout used by OS X, or with keyboard shortcuts for common programs including Adobe Photoshop and Final Cut Pro, as well as blank translucent skins in many different colours.
Made of flexible silicone, the TypeOn skin is washable and durable; it helps protect the keyboard from spills, dust and crumbs.
So they won't make your keyboard completely waterproof, but they'll help protect it from crumbs, spills, and drool. The website lists skins available for the desktop keyboards, bluetooth keyboards, and for the PowerBook, iBook, MacBook, and MacBook Pro laptops.
