Jesmonite Flex Metal Gel Coat Set in the colour of copper is a top-notch two-component composite material. It contains real metal powder and it resembles a copper look on the surface of decorative objects. By applying a 2 mm layer into a mould and adding the AC730 material, a strong, durable and unique casting is made. You can polish the surface of the cast by hand using fine wire wool to achieve a high metal shine.
