ABSTRACT:
A protector article and method of forming the same for use as a paint mask or water shield. The article comprises a generally flat and relatively thin sheet of flexible plastic material having its peripheral edge shaped to conform to the shape of the surface to be protected. Adhesive is carried by the peripheral edge of the sheet to allow it to be permanently or temporarily connected to the surface to be protected. At least one predetermined area in the sheet is enclosed by a series of relatively small and closely spaced corrugations to allow the enclosed area(s) to be selectively deflected laterally of the plane of the sheet to form pockets or bulges to allow the sheet to generally conform to discontinuities in the surface being protected. The corrugations are preferably formed by conventional thermoforming techniques.
