I used Gyeon Quartz Leathershield, CarPro also makes one but I've read the reviews and that it yellows lighter colored leather. It was easy to apply, clean the seat, wipe it on and it cures in 10 minutes (summer). I did the seats, center console and door panels, anywhere bare skin would touch
Leather coat is the small bottle on the floor, I use it solely for maintenance for the Ceramic coat so it last longer. Its been on since the day after I got the truck, July 20th, so far the seat looks new, 7K miles. No wrinkles, no issues so far
