Picked up a 1/4" stampped aluminum "skid" plate for my '18. Mostly just for medium duty protection of the plastic transmission pan from road debris and seasonal roads... Some people have mentioned minor NVH issues with it, though, so I'm considering spraying it with a coating to dampen and ringing/NVH/whatever. Looking at either your standard rubberized undercoat, cheap spray on bed liner or flex seal... No idea if any would be more effective than the others although since have a spare can of flex seal somewhere I'm leaning that way.
