Engineered for plastic and coated materials, these compounds cut and refine surface imperfections when paired with appropriate cloth buffs. Starting with coarser grades such as TRIPOLI and progressing to finer DANDEE compounds improves clarity and increases surface luster while preventing burn marks.
