Features: brand new and high quality Our airway polishing wheel is made of 40 layers of cotton and is specially installed in the center of the steel ring to form wrinkles on the surface of the cotton. The wrinkles make the polishing wheel run cooler, thereby keeping the polishing surface cool. This allows you to polish longer than the standard for buff. Airway polishing wheels are usually used to replace standard spiral stitched polishing wheels. The stiffness of these Airway polishing wheels is similar to that of spirally stitched polishing wheels. Airway design allows you to polish longer and cooler than standard polishing agents. Use with polishing agent.
