Ceramic coatings are like a high tech sealant put on the entire car. It will cost you close to $1k for a pro job. I have seen cars that had it when I had my Z06. Rain hits your car and just rolls off in a sheet, doesn't even bead. Pretty amazing. The stuff Andy mentions is clear bra - Xpel is the big one out there. Had it on the Z06 and have it on the wife's Q5. You can cover just the bumper or get the whole front clip done like I did. Bumper, full hood, front fenders, mirrors and door sills. In hindsight I would have done the rear bumper too as she is not real careful loading and unloading stuff out of the back. The stuff absorbs rock chips and the like and keeps the paint perfect underneath. You can't tell it's there. Professional installation makes all the difference. Have them roll the edges if you get it done.
