Are you sure this stuff won't stay adhered underwater?
They claim the coating is more durable that previous coatings. Not sure what that means. The Tabor abrasion scale numbers they quote look about like PVC, but I have no idea what that means when for a very thin coat stuck to a fast moving boat bottom.
A quart (each) would cover a Seacraft. If it reduced drag a whole bunch,stayed on a month or two and you run a lot of gallons of fuel, it might much more than pay for itself.
