ABSTRACT:
Masking material of particular value to vehicular surface coating operations consists of a thin, flexible base sheet having opposing first and second longitudinal edges which define a width. A pressure-sensitive adhesive layer is applied longitudinally along at least the first edge on the inner surface of the sheet with a width substantially less than that of the base sheet, the base sheet further including a longitudinal area on its outer surface and along the first edge which functions as a release layer, enabling the base sheet with adhesive layer to be provided in roll form and easily removed therefrom for use. In an alternative embodiment, a second pressure-sensitive adhesive layer may applied longitudinally along the second edge of the sheet, this second adhesive layer also having a width substantially less than that of the base sheet, and the base sheet further including a longitudinal area along the second edge on the surface of the sheet other than that on which the adhesive layer has been applied which functions as a release layer. The material may or may not be adapted to withstand oven temperatures of the type used, for example, to cure paint.
