If you do decide to go with the tracwrap, which I also wholeheartedly recommend. Make sure you bring a spray bottle you can fill with water. Spraying the panels with a lot of water helps the application significantly.
Also with tracwrap you can get it to look pretty good. The film was super durable and thick. But I also realize why PPF installs cost so much, to do a great job, it took such a long time
