With he recent introduction of marine specific gelcoat ceramic, I am curious to hear from folks that have used them and how they are holding up. I have already seen Mikes posts about his boat detailing classes and his 3D ceramic installation but I would like to hear from other folks on their thoughts from application to durability of some others like:

CarPro Nautik
Gyeon Q2R

I have used CarPro UK3.0 on a couple of boats and have not had any complaints but neither of those two boats get much use and when they do its freshwater.

If you have experience with any ceramic coating in heavy saltwater use, it would be greatly appreciated.

Thanks
