I have done some research on this as I wanted to get both my Challenger and my Solstice ceramic coated. I have found out that 'IF' you don't have a show room condition paint, that EVERY single little mark will magnify with the ceramic coating. I wanted this because I was getting new T2 black strips installed and didn't want them to split or chip like my current ones are doing. But, when I found I needed a show room new paint on my car, I decided against it and went with good ole Meguiars. If your car has less then 5k on it, it's probably worth it, but if you have any rock chips, dings, dents, etc....it won't turn out too nice. I did read an article of a guy that had his Nissan GT done at 6k with tons of rock chips and it turned out horrific and he sued the installer for $50k because he had to have his car repainted and it devalued it.
