During bike week a ceramic guy had a stand 5
r so years ago.
We were doing a ton of boat recons and he presented his schtick. I forget the volume of the containers but they weren't cheap.
I said repeatedly give us one to sample and we will know whether it works. He wouldn't spare one container so we never tried it and went on with acid treatment for waterline followed by traditional buff with compound and wax.
He could have sold quite a few if it was a shortcut to a better looking boat that held up.
