I did mine myself. Mostly on my own the first time, I have done it twice now in total. Materials was 1080 Matte Black air release 3M vinyl from Vivid Vinyl from Amazon.com.
First time was passable with one trouble area that bugged me, so I did it over and now I am very happy with it.
Go slow, use a heat gun or hair dryer sparingly to avoid overheating the vinyl. I used almost no heat the second time around.
It is a big project to tackle alone and to learn on. First time took me 3.5 hours, second attempt took 1.5 with a buddy helping me control the film some with me working it down. Then I did a buddies 2012 SS in an hour with him assisting. Goes faster each time.
In the first pic you can see how you need to have enough to overlap all sides. I used a 6'X5' wrap. Once you get it layed down, work the air slowly. I worked from the hood center point out both sides, did the center cutout last and then trimmed the rest when done. Having an extra hand to lay this down helps a lot. You want it tight like a sheet stretched across the hood and then work the air out slowly. Having someone hold the edge of the vinyl open for the air to escape makes for a very clean install.
