ABSTRACT:
A method for simultaneously forming and applying a plastic liner to a truck bed is provided wherein a sheet of plastic material is brought into engagement with walls surrounding a truck bed, heated to a pliable state, and forced into close conformity with the contours of the bed by the application of a vacuum from beneath the sheet and/or the application of pressurized air above the sheet.
