50/50 Wool Acrylic Polishing Pad This wool pad has 50% 4 ply wool and 50% single strand wool/acrylic blend. This combination makes a light compounding/polishing wool that removes minor oxidation, haze, dullness, and spots. The 50/50 pad has 1 ½ inch twisted threads, which are less aggressive than the shorter twisted threads found on the compounding pad. Use this pad with Wolfgang MetallWerk™ Fine Aluminum Polish.
