I have PPF installed on my Lucid Air, and I’ve found that using a blue scrub pad to scrub the PPF works exceptionally well. I typically use Sprayway window cleaner and let it soak for a while before scrubbing and wiping the surface. All my cars have PPF installed.
Since I’m leasing my Gravity, I’ve decided to defer using PPF for the time being. Bug cleaning has been a significant challenge, and I need to find a gentle method to soak the front end that won’t damage the clear coat. Additionally, all the crevices are difficult to clean. I’ve also encountered bugs trapped in hard-to-reach areas, such as the edge of the Lidar. I wonder if it’s possible to redesign all the sharp crevices and smooth them out without compromising the car’s aerodynamic performance. Although, some of the issues are attributed to the numerous plastic components and the tiny cracks where they fit.
