The image above is an excellent demonstration of the effect wet-blasting, or vapor blasting to give it its other name, has on composite surfaces.
Note how the water evenly sticks to the clean wet-blasted area on the right and is repelled from the un-finished surface on the left. A similar effect occurs with adhesives, lacquers, and paints.
It also explains why wet-blasting composite surfaces is important for maximum composite bonding strength.
