To chime in:
Because my last car got it's hood rock-eaten over the years, I literally drove directly from the dealership to the clear-bra installers. I went with a shop that uses VentureShield.
Pros:
Thin, only visible from very slight angle.
Lifetime warranty (if it peels, they'll replace it, anywhere in the country)
Cons:
Installation is shop-dependent. If they're bad at it, you'll either have to make them redo it, or in some cases, shops cut the bra on the car, scoring the finish.
Self-installation is possible, but requires an extrememly clean area and some luck/skill. (I bought a Nu-solis screen, and then decided that it wasn;t a good idea...)
My shop did a phenomenal job, and I haven't had any issues. Unfortunately, the only rock I've had hit my car shipped the windshield.
