My Acura was a great test for me as the ceramic held up far better than I thought. On the XC40 and C40 I have PPF on the grill area. If you do a lot of highway then loom at PPF for bumper, grill, front parts of quarters and maybe front foot or so. The key to keeping ceramic last is no harsh chemicals,and no brushed car washes and no vigorous drying. Before I got the air dryer I would just drag the waffle weave cloth across the car and it soaked up water. The ceramic makes it easier to clean as well. I went from snake oil skeptical to believer. Been very happy with Gtechniq Crystal Serum Ultra. If you do it, find a certified place that does it as then the warranty is enforced if dealer goes bust or you move.
