Product Overview
Polarstar SR is the first in a series of high-technology micro products produced by Mirka. This innovative curing technology is energy-saving with a low carbon footprint. This film abrasive is mainly developed for spot repair, used at car plants in the finessing- and hospital area of the paint shops. The Polarstar SR products are also used in the automotive refinish processes. This product is primarily designed for wet sanding, for correction of small painting defects and removal of dust particles in top coats and clear coats. Suitable for both machine and hand sanding.
Spot sanding discs are designed to be used with Mirka’s 30mm pneumatic or electric sanding tools when sanding small defects to quickly refine the surface, or to get into small areas that traditional sanders cannot reach.
