Abstract: A process for covering a paint tray so that it may be reused without the necessity of cleaning. The process involves the placing of a flexible, paint-impervious bag over the entire paint tray before any paint is placed therein. The bag is sufficiently large so that a portion of it fits against the interior of the tray and is of sufficient length so that it extends past the end of the paint tray. After the paint tray has been used, the plastic bag is completely reversed thereby capturing and containing all the paint that was formerly in the tray leaving a completely clean tray.
