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. ## Claims ### Claim 1 A paint tray and liner kit, comprising: 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 defining an initially-interior paint well and initially-interior ribs, the initially-exterior surface defining a male curvature removably received in the female receptacle of the paint tray; and wherein: the initially-exterior surface defines initially-exterior ribs adjacent to the initially-interior ribs, and 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 by application of hand force to the initially-exterior surface; and wherein 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. ### Claim 2 (depends on 1) The kit of claim 1, wherein a top edge of the initially-interior surface is free of laterally-extending structures. ### Claim 3 (depends on 1) The kit of claim 1, wherein: the female receptacle of the paint tray includes recesses; the initially-exterior ribs are removably received in respective ones of the recesses; and the initially-interior ribs are positioned relative to the initially-exterior ribs such that the initially-interior ribs are removably received in the respective ones of the recesses while the liner is in the inverted state and the curvature of the liner is removably received in the female receptacle of the paint tray. ### Claim 4 (depends on 1) The kit of claim 1, wherein: the paint well is defined by a bottom surface that has a plurality of sides and a sloped surface extending from each side of the plurality of sides; and each of the sloped surfaces extends at a slope that is between 1.0 and 0.3. ### Claim 5 (depends on 1) The kit of claim 1, wherein the liner is made of polysiloxane. ### Claim 6 (depends on 1) The kit of claim 1, wherein the material from which the liner is made and a thickness of the material are selected such that the liner is invertible between the uninverted state and the inverted state between one and one hundred times. ### Claim 7 (depends on 1) The kit of claim 1, wherein: the initially-interior surface of the liner defines at least two sloped sides; the initially-interior ribs include a first set of ribs that are on one of the at least two sloped sides; and the initially-interior ribs include a second set of ribs that are on another one of the at least two sloped sides. ### Claim 8 (depends on 7) The kit of claim 7, wherein the first set of ribs is substantially perpendicular to the second set of ribs when the liner is stationary in an upright position on a flat horizontal surface and is viewed in 2 dimensions from a point directly above the predominant face of the liner. ### Claim 9 (depends on 1) The kit of claim 1, wherein: the liner includes a first identifier on the initially-interior surface and a second identifier on the initially-exterior surface; and the second identifier is different from the first identifier. ### Claim 10 A paint tray liner, comprising: a body shaped to substantially conform to an interior surface of a paint tray while the body is in an uninverted state; wherein: the body is structured to be invertible between the uninverted state and an inverted state without perforating the body, the body defines a paint roller surface with ribs, and the body is made of a material selected such that the ribs are invertible without perforating the body. ### Claim 11 (depends on 10) The paint tray liner of claim 10, wherein the ribs have a footprint that is sufficiently large to enable the ribs to be invertible without perforating the body. ### Claim 12 (depends on 10, 11) The paint tray liner of claim 10 or 11, wherein the body has a thickness that is between 0.45 millimeters and 2.00 millimeters. ### Claim 13 (depends on 10) The paint tray liner of claim 10, wherein the body is made of an elastomer.
