My dealer in Ottawa, Ontario offered me a protective clear coat for my car. I said "Definitely". It is done by ClearShield,
www.clearshield.com, and it is guaranteed for 5 years. No discolouration under the film, no peelling, no rock chip marks, hardly noticeable. To get the front 8 to 12 inches of the hood, whole front bumper, back of mirrors done will cost $500 Cdn. Which is approx $425 US. Well worth it. You can wax it, buff it, and do your normal beauty care as you normally do.
