I got my '19 done when it was new. It was around $1000 for a 5-year package.
I didn't have to pay any extra for any paint correction as the truck was new. That truck was black. When I traded it in 3 years and 73K miles later, the paint still looked better than new. It made me a believer in ceramic coatings. Especially on a black truck. I can't remember how long they kept my truck. I want to say it was just 1 day, but it could have been 2. I don't think it was any longer than that.
I liked the results so much that my '21 is scheduled to go in in a couple of weeks. But, I have moved and around here, the 5 year coating is going to set me back $1900. And, being that the truck already has over 20K miles on it, they recommended 2 stage paint correction first, which I concurred with. So, all in it's going to be $2100. But, my '21 is also black and I know I will regret it later if I don't get it done now. With the paint correction and the coating, they said they want to be able to have my truck for 4 days.
I got the windows tinted (35% ceramic film on sides and back) by the same place earlier this week. With the ceramic coating on the paint and my Helo wheels just waiting to go on, I will be very, very happy with the overall looks of my truck.
