Is there a non-silicon skin for MacBook Air keyboard?

For some of us who are truly obsessive, is there such as a thing call skins to protect the MacBook Air's keyboard? I am not looking for silicon-based covers such as those covered in previous threads (like the iSkin keyboard cover). Rather, I am looking for solutions similar to Zagg of Best Skins Ever that use 3M like materials to protect the entire keyboard or individual keys.

(Just in case someone brings this up... I am aware that one may require to skin all the keys on the keyboard one key at a time... 😀)
