I am writing my doctoral thesis for the University of Wazoo....okay I'm not.
I am having some ceramic coating done to my old truck resto & will ask the folks at Jet-Hot if the marine applications would be suitable for the intended use also any ability to fair the cast iron (what will/will not work as fairing material if any) prior to coating.
Stay Tuned- (great name for a boat BTW) don't hold yer breath.
