Abstract: A paint tray and liner kit is provided. The kit includes a paint tray having a female receptacle, a liner in an uninverted state having an initially-interior surface and an initially-exterior surface opposite the initially-interior surface. The initially-interior surface defines an initially-interior paint well. The initially-exterior surface defines a male curvature removably received in the female receptacle of the paint tray. The liner is sufficiently flexible such that the initially-interior paint well is invertible from the uninverted state into an inverted state without perforating the liner. This may be done by application of hand force to the initially-exterior surface. In the inverted state, the initially-interior surface is an exterior surface defining a curvature that is substantially the same as the male curvature that was defined by the initially-interior surface, and the initially-exterior surface is an interior surface defining a new paint well.
