I have close to the same black truck, had all the gray stuff painted including the tailgate appliqué. It was all fine, just FYI, the applique has a bit of a pebble grain profile the other stuff didn’t have. The paint shop had to do a couple extra coats of clear to make it look just right. Don’t let somebody else’s opinion about what looks right deter you, it’s your truck, do what you damn well want. Others can leave theirs stock on their truck if they wish, who cares what they understand or don’t.
