Invisi-shield, leather, plastic, arg........ tons of them!

Well I decided the iPhone is too purty to cover up, so I'm going to use a clear wrap. I have seen so many that it is hard to decide which to use.

I want one that won't peel up, and will be extremely clear. I do not want an adhesive one unless it peels off clean.

If it were available I'd buy one like a clear shrink wrap that you slide over it and just heat up. That'd be awesome.

Which do you use.
