Ok, so I recently decided to take all the assorted stickers I have and put them on the back of my 2nd gen MBP. I want to get some sort of clear protector to put on first though, just in case I get tired of having the stickers on or I want to sell it. I want it to fit on like a big sticker on the back, without adding bulk obviously. I've already looked at the Invisible Shield, which is similar to what I want, but I've used those on ipods before and when you take them off it leaves a gross residue I had to scrape off. So does anyone know of a clear, sticker-like protector I can put on the back of my MBP and take off without leaving any residue? Preferably cheap.
