Agree with stealth.pilot, the Xpel is the only way to go, this is the second car I've had it on and have been pleased both times. I posted one pic from yesterday after my install. I've seen installation prices very from 1200-1500 on a job similar to stealth's as well as mine, agree it depends on where you live.
