Tamiya have introduced a set of three polishing compound sponges. Top modelers use small polishing sponges to remove any irregularities, thus creating a stunning finish. They may be used with your favorite polishing compound. They allow for clean, precise application of the compound, giving your model a gorgeous finish to its paint job. The sponges feature integrated grip sections, making them a breeze to handle and compared to cloth, the sponges allow much more precise application of polishing compound, helping to prevent problems such as rubbing away paint from corners or edges, and accidental mixing of colors on or around borders. The set includes a small, a medium and a large sponge that can be washed and re-used.
