The interior protection is a nice feature. I detail a ZR2 Colorado for a client that had a similar package done on his truck. It’s held up well after a couple years now. But in my experience the exterior coatings are not worth the money they charge to install it. A lot of dealers, at least here in California like to use CilaJet coatings, which is what’s currently on the ZR2 Colorado’s exterior. and for that kind of money there are much better, and longer lasting coatings available on the market. I’ve had several clients over the years with dealer installed CilaJet coatings and it never last more than 2 years or so. And it just doesn’t perform as great as many other coatings. It doesn’t bead up anywhere near as well and honestly doesn’t bring out the pigments in the paint to give it that nice top tier level shine.
