Cylinders with a central axis to which filaments of different nature are fixed. Those made of natural or vegetal fibre bristles are used to remove excess stain (not dried yet) and obtain the so-called “tear effect”. Nylon abrasive ones are used for dry-sanding basecoats. Those for polishing polyurethane or polyester coatings are made up of cylinders covered with tightly tied cloth rings. Polishing is carried out using abrasive waxes or pastes.
