An in situ vehicle bed liner together with a method for production of the liner is provided. A vehicle bed is prepared by sandblasting and cleaning, and surfaces adjacent to where the liner is to be formed are protected. A two component polyurethane, polyurea or polyurethane/polyurea hybrid is utilized to create the liner, with the two components maintained separately until application to the vehicle bed. A spray gun is used to create the sides of the liner, mixing together the two polymer components just prior to exiting the spray gun. The polymer composition reaches it gel point almost immediately upon contact with the vehicle bed to prevent running or sagging of the polymer material. The polymer is sprayed on the sides of the vehicle bed to produce contiguous sides of the liner and allowed to gel. The two component polymer material is then poured on the floor of the vehicle bed and adjoins the polymer sides of the liner to produce a contiguous liner. The polymer is then cured to form the vehicle bed liner.
