A northern climate vehicle should be protected on all leading edges.
The fim on my '05 was removed after 120K miles. The paint is PERFECT underneath the film. The paint is damaged where exposed. Cover everything.
My vehicle was protected on: the leading hood edge; the front bumper; the headlights; the fog lights; the mirrors; the door handle cups and behind the rear wheels.
The 1/8" exposed perimeter, at the film edge, has sand-blast damage.
Also, removing the adhesive is a pain in the butt, after removing the film, but well worth it.
