Having thus described the invention, what is claimed is: 1. In an agricultural round baler having a multi-component dispensing mechanism for wrapping a bale with stretch film from a roll thereof, some of the components having surfaces that contact the stretch film during the wrapping process, the improvement comprising: each of the surfaces of the dispensing mechanism that contact the stretch film is roughened by a layer of paint containing a grit-like material to reduce the wettability of said surfaces to thereby prevent the stretch film from adhering to such surfaces. 2. The improvement of claim 1, wherein: the dispensing mechanism is alternatively capable of dispensing netwrap material from a roll thereof. 3. A round baler for forming crop material into cylindrical bales, said baler comprising: a wheel-supported main frame including opposing longitudinal sidewalls; a bale-forming chamber having a generally cylindrical shape with a transverse inlet and a crop-engaging mechanism disposed between said sidewalls; a crop feeding mechanism for feeding crop material into said chamber through said inlet whereupon said crop material is engaged by said crop-engaging mechanism under conditions where said crop engaging mechanism is moving along a portion of said periphery to engage said crop material and form it into a compacted cylindrical package as crop material accumulates in said chamber; a multi-component dispensing mechanism for wrapping the bale with a sheet-like material from a roll thereof, some of said components having surfaces that contact the sheet-like material during the wrapping process; and each of said surfaces of said dispensing mechanism that contact the sheet-like material to reduce the wettability of said surfaces is coated with paint containing a grit-like material to thereby prevent the sheet-like material from adhering to said surfaces. 4. The round baler of claim 3, wherein: said sheet-like material is selectively either netwrap or stretch film. 5. A method of preventing stretch film from adhering to the surfaces of an agricultural round baler wrapping mechanism comprising the steps of: providing an agricultural round baler having a multi-component dispensing mechanism for wrapping a bale with stretch film from a roll thereof, some of said components having surfaces that contact the stretch film during the wrapping process; and treating said surfaces by the addition of a layer of paint containing a grit-like material to reduce the wettability thereof sufficiently to prevent the stretch film from adhering to said surfaces.
