venture shield durathane film in Minnesota?

Does anyone know of any places in Minnesota or the surrounding region that will apply the venture shield durathane film. I have heard this is superior to 3M. Also, I had imagined the entire (or 3/4) of the hood to be covered with the film, but was told it was only 18 inches. Does that sound right? The quote was $700! Is it really worth that much money? Has anyone applied this themselves? Thanks for the info. Bea
