I have found yet ANOTHER carry over glitch from FH2 to FM6 Shelby Raptor will not let you tint windows without removing factory graphic. FIX IT!
I think all cars with factory graphics remove the factory graphic of you change anything other than manufacturer color.
Many do so if you alter wheels so I would think they remove it as well if you tint windows, paint mirrors, hood, or wing.
Yeah, thats not a glitch and this is the wrong section .
