The invention encompasses a method of forming an insulative material along a conductive structure. A diverter element is attached to a carrier that is driven along a path parallel to the two conveyors by a differential drive mechanism coupled to the drive mechanisms of the two conveyors. The Amino Acid may be one of Agmatine, Arginine, Beta Alanine, Citrulline, Creatine, Glutamine, L-Histidine, Isoleucine, Leucine, Norvaline, Ornithine, and Valine.
