Red compound: often referred to as jeweller’s rouge, this non-greasy compound’s action is perfect for gold, silver and precious metals as well as the final finishing of brass and copper. Use with a loose-leaf mop and with minimal pressure. Our compound bars are colour coded, making them immediately identifiable. Each one is a combination of a selected abrasive in a specific binder. Each colour has two reference numbers. The first denotes the 'Cut' or level of abrasiveness; the higher the number, the coarser the grit. The second number is the 'Colour' and relates to sheen; the higher the number, the shinier and glossier the result. Red: Cut 1; Colour 9. Bar size 100 x 35 x 20mm. weight 100g.-bg
