Check out the channel Dip your Car on youtube, it's ready to spray plastidip. These guys do amazing colors and paint jobs using this removal plastic coating and it's usually much cheaper over a wrap. If you don't like it, then you can peel it off when you want to move on. The big caveat is to make sure you put down enough layers, usually 6 is the minimum for durability and peelability. I've seen pics of people getting into fender benders, panels were crush, but no chips or tears in the plastidip.
I plan on doing my Firebird and my wife's Jeep Liberty this summer.
