Have any of you had your rear spoiler feel loose? When I dried my car the last time I washed it I notice the right side of the rear spoiler was loose. The nuts have something black on them and the side that's loose I can unscrew with my hand. I could just tighten it with plyers but I don't think that is how they want it to be done. Does anyone know if there is a tool you should use to tighten them and what to torque them to?
