Technician A is correct. A guide coat is a contrasting color that is applied over a surface that is to be sanded to help the technician identify any low spots or imperfections during the sanding process. Technician B is incorrect. Metal cleaners and conversion coatings are not a substitute for an undercoat before topcoating. An undercoat helps to provide adhesion and proper coverage of the topcoat.
