I wrapped the front end of my rainforest green. These new PPF films are pretty amazing. I had some bird droppings that I cleaned off after a day, and I could see the etchings of the dropping after I cleaned it off. The installer had told me to give the film a chance to self-heal before trying to use any rubbing compounds.
Without the PPF film, a bird dropping left to dry on the paint will leave a mark which you can see when viewed closely. Bird poop etches the paint. After a day in the sun and heat, the PPF actually self healed. I can't see the etching of the bird dropping so I won't need to hit it with any type of gently rubbing compound.
I have Suntek Ultra installed. I have 15 year old 3m film on another car, and there is NO WAY those old films would "self-heal." The new films they have nowadays are really amazing.
If I had a black car I would consider wrapping the entire car. I know black cars show every little scratch and as careful as anyone can be, it doesn't matter; a black car will start to show fine scratches over time. So you either have to get it detailed and polished out every so often, or maybe a full wrap of these new films would protect the paint from those fine scratches that really mar darker color cars.
Ask you local installers if the PPF films will drastically minimize the scratches that so easily show up on black cars.
