I want to try and make my 2013 xlt look like an undercover cop car. That's the goal. The undercover explorers don't have the roof rack rails on them but if I try to remove them, it leaves somewhat of a gutter where they sit. I've tried looking for some sort of plug or cap for them since I don't want it to cause a leaking issue. Plus the roof rack rail base on the front comes down to the top of the windshield so you can see the white plastic that's underneath from the front. How would I go about plugging the gutter?
