7/10 installs say 3m is garbage, and they refuse to use it.
Its over priced and turns orange really fast.
The top tier PPF that i have learned is nanofusion and xpel.
I have had 2 installers litterally argue on what is better with some saying NF is the ultimate, while others saying Xpel has better endurance.
I have seen both, and on a dark colored car, both looks good, however on a white or blue car, i believe possibly NF might look better as it seems to have a clearer look.
Suntek was told to me that its a bargain option incase one can't afford Xpel.
Something one would possibly want to do on a car that is either leased, or your going to trade in soon.
Either way i have full coverage Xpel on my P100D.
It has saved me a few times, my dog has jumped up on my car, and what normally would of been scratched due to her claws, it was saved by xpel.
I also live in a dense metro area, which undergoes a lot of construction, and have had tiny pebbles thrown at it from the car in front, and so far no damage is seen on the PPF.
I went though a reputable authorized installer, so i also have the full warranty on the film and the work as well.
The total price on it was enough to put down on a luxury car, but i intend to keep my P100D for a while, until another sub 3 second 4 door sedan comes out....
