A proud new owner of my third Genesis(12,15,18), all with the Ultimate Package. My black 2018 Genesis Sport 3.3 T has a bronze/copper colored trim around the side windows. The trim seems to be quite porous & shows water marks and/or any kind of sealer/protectant I've tried to protect it with will dry to dark spots. This doesn't happen with the normal shiney chrome plastic trim, like on my door handles. Other Sport owners have said the same thing. What's the solution?
