Duetto is equally effective working with soft or interface backing pads teamed with micro-abrasives during the defect correction step or with foam polishing pads and compounds during the polishing stage. Extensive research on random orbital dynamics and exhaustive testing resulted in the choice of a 12mm orbit for Duetto. This orbit length greatly improves the surface rectification abilities of the latest generation of microabrasive discs. The combination of duetto and microabrasives is especially effective when smoothing orange peel or significant defects. The finish generated by this combination is both homogeneous and predictable, with no deep sanding marks.
