Hi Suke, I've e-mailed him so might have an answer soon. I've seen posts on the forum about ceramic being snake oil etc, but I figure these are people who haven't seen it in action. I've seen it on a number of boats now in South Florida and as an old school sceptic at first, I'm a full convert now. I worked on a boat that had spent six months in a large and particularly dirty boat yard and the boat looked like it needed to be scrapped, it was black. The boat yard is by busy roads and sits underneath a flightpath as well so wasn't looking forward to cleaning it. That baked on dirt and chemicals washed straight off to leave gleaming gelcoat, then when it had seen the light of day, water started beading straight off it again. I also know for a fact that the ceramic hadn't been applied particularly well because I enquired about the process. That was about a year ago and the ceramic is still going strong. It's worth noting that subsea pipelines are coated in this stuff now, so yeah, it works ok. I think it's one of those things, you just need to see it with your own eyes.
