I'm thinking about doing my own roof wrap, but there are a couple things I’m not sure about. 1. The bushing around the shark fin. How does it fit on there? Is it reusable or do I have to get another one? 2. The inner grooves on either side of the roof. There seems to be a small piece of weather stripping in these grooves. How do you wrap these? Does the vinyl wrap tuck in there nice and neat? I assume you don’t cut the wrap at this seem, the wrap goes all the way across the roof from rail to rail? I’ve tried to find videos on YouTube, but I haven’t been able to find any other cars with a roof like the Stinger.
