ABSTRACT:
A method for modifying a surface to a desired contour by pressing a flexible molding plate, having holes for releasing trapped fluids and excess molding compound, is pressed on a molding compound by a plurality of ordered pressure points which are set to define a shaped plane corresponding to a desired contour. The pressure points are adjustably included in a support frame, or are provided by shaped rollers. Compound extruded through the holes by the operation is removed from the plate which is then removed. Nubs resulting from excess molding compound in the holes are removed by sanding or other finishing means.
