This stuff looks interesting... http://3mauto.com/products/paint-de...nalLink&utm_content=homePageButton_top_lerft/ http://www.amazon.com/gp/product/B0..._m=ATVPDKIKX0DER&pf_rd_r=1B5Y3W28RVHC4SFXBMSD
It's a good product and does protect well, but is not invisible. I work for 3M and had a chance to play with it in the lab a bit and noticed a distinct haze on the test vehicle. If I was overly concerned about protecting my paint, I'd choose the film over this.
I've been curious about this stuff myself. I have the clear bra film on my sti, but it picks up cone marks easily, they are hard to remove, and the film isn't cheap/easy to replace. If this stuff applies and removes as easy as plasti dip, I'm very interested.
