ANEW product of the B. B. Chemical Co., Ltd., Leicester, manufacturer of Bostik compounds. and of British Cellophane, Ltd., enables joints in bodywork to be sealed in an unusually effective and clean manner. Use is made of Prestik sealing compound which is extruded in the form of a corrugated strip.
This is fed on to a Cellophane film from a roll. Compound and film are then wound together into a roll, the Cellophane acting as a backing and as an interleaving agent. When a joint is to be sealed, the compound is placed in position on the joint and is pressed into position. The Cellophane is then peeled off, leaving the seal clean and ready for painting or other treatment.
