PolishingStiX turns a material into a professional modeling tool!  Part #1107 Each five matchbook set contains six PolishingStiX in grades 3200, 4,000, 6,000, 8,000 and 12,000. PolishingStiX is real Micro Mesh with a stiff, pliable polystyrene backing. You can trim each stick to fit any minute detail requiring the same polished surface the rest of your build demands. The plastic backing allows you to dip PolishingStiX into water for cleaning and reuse to achieve that wet sanded sparkle! Perfect for removing embedded dust particles that seem to appear in that last wet coat of spray paint. Cheaper than a set of Micro Mesh sheets alone! Sold only as a five matchbook set, matchbook grades are not sold separately. Car body model not included with PolishingStiX, duh!
