I've gone back and forth on this and realized PPF isn't worth doing unless you wrap the whole truck. The most vulnerable areas; the front filler panels, hood, rockers, and rear fenders, already cover most of the vehicle. (don't think you can wrap the textured black parts)
"Half-measures" don't work here. A partial panel wrap is a bad idea because dirt and grime build up along the cut line, making it peel. And if you commit to doing all the vulnerable full panels, you’ve already covered the hood, doors, rear fenders, and cab. At that point, the front fenders are the only things left exposed, so you might as well just finish the entire truck.
You will also need consideration If you have decals. PPF over the decals will make them glossy instead of the matte look. Will also leave a "halo" around the decal as the raised surface will create a small air pocket. I would recommend removal and decals on top of the PPF.
