• at least one fluid inlet connected to the body portion that provides a conduit configured to pass pressurized masking fluid from an exterior of the pressure masker to an interior of the pressure masker, wherein the first side of the at least one passageway of the article is at least partially disposed within the interior of the pressure masker;
• and,
• at least one seal that seals the body portion at least partially around the article such that the pressurized masking fluid that enters the interior of the pressure masker is at least partially forced through the first side of the at least one passageway and exits out the second side of the at least one passageway.
