dlittle, here's my take on it I have over 30000 real-world miles on my '14 Z51, and I do not have any protective film at all. This includes narrow 2-lane paved farm roads to 8-lane interstates, from Bowling Green, KY to Houston, TX to Denver, CO to Las Vegas, NV, in rain, show and shine. The patterns of nicks & chips I see include the following areas:

1. Pretty much the entire front fascia. For cars with splitters, cover them too.
2. Coupe roof panels - they can see minor scuffs from repeated removal or extensive use of a cover outdoors. I would especially cover an exposed carbon fiber panel.
3. The rockers. Remove the small clear film applied at the factory, then cover the ENTIRE rocker, from front of door all the way back to rear wheel well and up to body seam. Also wrap the film into the door jambs, especially at the lower rear corner where the gap curves up to the body crease. That edge doesn't stick out far, but it really takes a beating. For Z06s, this includes the rear brake duct inlet.
4. The door sill area, including the aluminum sill plate. They catch lots of shoes, and even the smallest rock stuck in a shoe can leave a big scratch.
5. Rear spoiler, especially Z51 and wing-style pieces. They catch lots of luggage, belt buckles, etc.
6. The lower rear fascia directly behind the rear tires. This is painted all the way to the wheel well, and catch everything thrown off the sticky tires.
7. For convertibles, I suggest the tonneau cover. I've seen on C5 and C6 Corvettes scuffs from repeated top lowering and raising. Also a good idea if you participate in a lot of parades and carry dignitaries or children seated there.

Believe it or not, I don't see a single nick or chip anywhere on the hood, front or rear fenders or mirrors, but I can see where some areas of the country might. If you do the hood, do the entire hood. A partial hood wrap will leave a line that becomes more noticeable over time.
