Hi All....I am the happy owner of a black '07 f430. When I bought the car two years ago, I had a full detail put on it (Paint was actually in very good shape from my perspective), and then had PPF put on the front end, half of the hood and quarter panels, and the mirrors. Its held up quite well, and no yellowing that I can discern. The car is garage kept, and while I try to drive it every weekend, living in sunny S FL, it stays remarkably clean. So much so, that I have only had to wash it maybe 3 times in two years. I generally wipe it down after each drive with a reputable product from Chemical Brothers (like a quick mist detailer to remove the light dust). However, to keep the car shiny, I do wax it every 4-6 months. But, the question it, should I be putting anything on the PPF?, or simply wax the paint, as I have been doing? I had read some prior posts, and some people said leave it alone and others said was OK to apply some wax, as long as there were minimal chemicals in it. Any advice would be appreciated. thanks!
