So I've put on ceramic coat on quite a few cars now. Its been cool because i've gotten to test out a bunch and it is amazing to see the differences. For the Stinger I chose to go with 2 coats of Kamikaze Miyabi, and 1 coat of Kamikaze ISM. Warning though the ISM was by far the most difficult coating i've ever had to apply, if you haven't done it before, do not learn with that stuff. This is especially true given how many great coatings are out there that offer similar qualities but are vastly easier to put on.
Wish I had taken pictures of the differences in application.
So far i've been thoroughly impressed and i'm difficult to please when it comes to this stuff. This right now is my favorite but I previously used 22ple HPC and that was also excellent (bit easier to apply). I had it on my golf R for 2 years and it was still flawless.

Gtechnique Crystal serum with exov3 topping it was great. Have that on a friends car and two years later been perfect. I used Gyeon Q2 on my mother's car and was probably the easiest to apply and gave a great shine. Didn't have quite the hydrophobic results like the others, and longevity is too soon to say. I put on Wolfgang uber ceramic con my DD because WG's Sealant is well known as being one of the best sealants you can buy... and I wasn't impressed. Not only was it difficult to apply and take off, but longevity wasn't great and I thought the gloss was pretty meh.
