It cost me a little over $500 for everything. My friend installs these and cut me a pretty good deal. It covers the door edges, mirrors and probably 99% of the front end. It goes on like window tint. It has a glue that adheres to the body. If you want to get one I would go with 3M products. Venture shield makes some film too. I hear it is not as good or thick. I think Venture is around 7mm and the 3M is 13 mm. The installer's wife has it installed on her car and a rock hit the hood. It left a dent and the paint was still good. No rock chip.
I took some of his scrap clear bra stuff and put it on the screen of all my electronics that have screens(Camera, Portable GPS, and cell phone).
