Has anyone used the paint protection film kit that Tesla sells to be installed in front of the rear tires? When installed properly, is it very noticeable? It comes in both a bottom and an upper piece. Is it necessary to install both, or would just the bottom piece provide adequate protection? It is easy to remove if desired? I live in a snowy winter climate and already have the four piece mud flaps sold by Evannex and others. I'm wondering if I should get the PPF also. Thanks!
