Default Ceramic Coating on Props

From what I've read there is a lot of positive recommendation for ceramic coating on hulls and topsides. Does anyone have any data or tried applying it to props as a anti fouling coating? Also it sounds like it would help with anti-fouling for underwater light lenses. A very hard and smooth coating should help. Any thoughts or comments?

My thought is that it might cause significant cavitation while the coating constantly tries to push the water away from the surface. But just a thought I could be wrong.

Seems to me like "hard and smooth" is a perfect substrate for marine growth. Also " hydrophobic" does not mean "growthaphobic," but would also seem to become pretty meaningless when the surface is submerged. Finally, not sure how long the coating would last with the constant/frequent friction of moving through the water.

surely the chemists will chime on in....

The fact that they advertise it as antifouling sounds suspicious to me, if it where true nobody would use antifouling paints, it would become a world breakthorough something that did not happen, the closest product to a permanant antifouling is Silicone based antifouling, said to last at least 5 years with absolutely no growth ..........
