Came off of my Oxford 2018 GT. I painted them with plastidip. 6 coats of plastidip, and three coats of glossifier. They have held up extremely well. A few spots may need some touch up but nothing major. PlastiDip can always be pealed off. Absolutely no issues with heat, or weather. The entire vent in black makes the car look really menacing. You will have to reuse the shroud and clips from your stock vents. The entire removal and swap is super easy and won’t take longer than 30 minutes and guides can be found online or I’ll walk you through it. Should work on all models of 2018 Mustang. Asking $180 shipped.
