Just a thought, but maybe you could use the clear plastic sheets they use to laminate documents?
Having said that, the only REO I own that actually shows any wear is a black (anodized) grand that was one of my first. It's "wear" is from the finish being rubbed off from so much use. But ALL the others I have are still pristine looking (Silver Anodized, Silver Hammertone, and White, plus a black anodized and silver anodized mini V1).
The finish, to me, holds up extremely well, but if you're gonna be giving it some rough usage due to work environment or whatever, maybe you should just get a leather case for it.
