Non-Ferrous Colouring Bar Compounds are intended for buffing non-ferrous metals where the work surface is in good condition, free of deep tool or die marks. The Compounds are made using quality grade material that ensures good quality. The Compounds are capable of providing efficient performance. The Non-Ferrous Colouring Bar Compounds are used extensively for buffing copper plated articles, particularly where a regular tripoli compound is too severe and removes too much of the copper-plate.
