Voidcoat

A type of ablative paint applied to the hull of a vessel to lessen the damage done by micrometeorites and other small impacts to the ship's hull. It tends to rub off onto anything that touches the hull, covering them in a thin layer that is hard to remove, some say it sticks to space suits and people considerably better than it does to the hull, leading to it's use as a term for someone who has spent way more time on a ship than is considered healthy.
