or cloth, but those adhesives apparently contain not only solvent, but small amounts of vinyl, or something very like it.
So when it is painted on the inside of the hull, it will at least form a mechanical bond with the surface. And the vinyl will be "sticky" to form a bond with the vinyl patch when it is applied.
If the inside of the hull weren't rough to begin with, and cleaned, and roughened somewhat to raise some fibers, I don't think the bond would hold very long.
Of course, I prefer bonding with epoxy, which is very compatible with the resins used to make the boat. But nothing succeeds like success.
