ABSTRACT:
A die-cut paint masking part for use in masking a curved corner surface of an object to be painted comprises a flexible, paint-impervious mask, a layer of pressure-sensitive adhesive material permanently adhering to the underside of the mask, and a removable flexible protective liner releasably adhering to the adhesive layer. Prior to use and while flat, the masking part has a generally Y-shaped configuration and includes a base leg from which diverge a relatively wide branch and a relatively narrow branch. The base leg and wide branch have a common curved first edge. The base leg and narrow branch have a common curved second edge. A notch or cut-out to facilitate folding is formed at the point where the two branches converge. The protective liner is provided with two score lines, formed during die-cutting of the masking part from a web, which define three independently removable liner portions. One score line is located near the free end of the base leg and extends between the aforesaid first and second edges. The other score line is located near the attached end of the narrow branch and extends between the notch and the aforesaid second edge. In use, the first liner portion at the free end of the base leg is peeled off and the mask is adhered to the curved surface to be masked. Then, the second liner portion, which covers the rest of the base leg and the entire wide branch, is peeled off and the mask is bent and further adhered to the curved surface. Finally, the third liner portion covering the entire narrow branch is peeled off and the wide branch is folded over and adhered to the outside of the narrow branch and to the curved surface.
