BMW X7

There's a lot of X7 to get right, and that's the whole reason a car this size is a good test. The doors, hood, and liftgate are all broad and close to flat, so an uneven finish doesn't hide in a curve somewhere, it shows up as a wobble in the reflection. We put Icon Rocklear on it, our permanent paint protection coating, and the panels came out deep and glassy, all of them, in one consistent read from the nose to the tailgate.

What most X7 owners actually want is for the car to still look like this after a few years of school runs and commuting, and they'd rather not book anything again to get there, which is the part permanent actually does for them. The details are on our Icon Rocklear page.
