The disclosure concerns methods and apparatus for forming an elongated product, having a high quality surface appearance and finish, from an elongated workpiece with a wax coating. The wax-coated, elongated workpiece is advanced toward, and then through, an aperture which extends longitudinally through a die, by an application of frictional drag forces, in the direction of the die, to the wax coating. The wax, however, does not pass through the die aperture, but rather is substantially completely removed from each successive element of the elongated workpiece, substantially as such element reaches the die.
